Follow Up on Flower Currency - What is up with his use of the 50-Peso Note?

So I was spending some more time thinking about Ian Grigg’s choice to pair a 50-peso note with the 100 Euro note in the flower currency video.

I do think this is encoded. The note he shows features Catholic priest and leader of the Mexican Independence movement Jose Maria Morelos. The town where he was born was renamed for him - Morelia, which happens to be the base of operations of Derek Broze in Mexico.

It is also the site of an 18th century aqueduct - water.

In the fall of 2021 Mexico introduced new artwork for the 50-peso note that won awards for being the most beautiful bank note in the world. It featured an axolotl a rare salamander that lives most of its life as a juvenile.

Julian Huxley did research into metamorphosis of the axolotl looking at manipulating its thyroid. Thyroid research has long used radioactive isotope tracking. It was around that time that he helped start up the biology department at Rice University. For a short time Huxley and Norbert Weiner were room mates in Houston.

I am linking Ian Grigg’s statements on the beauty of money to Eisenstein’s “Sacred Economics” and Celo’s push for “beautiful money.” Celo also imprints the word “prosper,” which to my thinking could be a reference to Prospero (like Nvidia’s MAYA programming software) the grand illusion.

All of these stories that are being woven around social impact tokenization of “public good” will enmesh us in perpetual soul harvest where are vital energies are used to run the machine.

I think corn is a part of this, too based on the research I did around Mexico’s conditional cash transfer program and the slashed tortilla subiside.

If axolotl is a stand-in for metamorphosis, then corn is target number one for genetic re-programming, an attempt to undue or pervert the central feature of Mayan cosmology. Which brings us back to the Dresden Codex @stephers.

Morelia is a center of quantum physics and radio astronomy, too. @leo

Curious if you can follow this line of thinking…or I am just too out there?

I don’t know - does that look like a black sun on that bill?

My main research interests are Quantum Gravity, Foundations of Quantum Theory, Quantum Field Theory and Quantum Groups.

Before coming to Mexico I worked and studied at these places:


Further thought on axolotls: they can metamorphose into “proper” land-dwelling adults, but this is very rare. The great majority of them don’t exactly live their lives as juveniles, but rather exhibit neoteny, which means that though they retain certain juvenile body features, and continue living in water, they become sexually mature. So you have a symbol of an adult living as, and looking like, a juvenile. The original note featured butterflies, which undergo a complete metamorphosis.

Huxley was working on triggering metamorphosis in axolotl via manipulation of the thyroid.

To me it feels like what Bernal proposed - larval state for 100-120 years then transfer brain to a cylinder for some weird perpetual “life.”

Early thyroid treatments of humans with radioiodine started in late 1930s.

I remember seeing a wall shrine to the origins of radioiodine therapy at MGH, when I was there debating nuking my own “toxic multi-nodular” thyroid. I was given the option of RAI or surgery. I opted for surgery which seemed scarier but safer, given the increased likelihood of developing kidney cancer, post RAI, later in life. It seems now, twelve years later, my thyroid is growing back, and I welcome it with relief. The thyroid is also, fittingly, shaped like a butterfly.

ADDON. Version 1.0. Released on 2021-May-19. Provides 65 components. Created by Mathias Bernhard. Features 0 video tutorials.

AXOLOTL provides a set of components for volumetric modeling in Rhino Grasshopper. They work based on the principle of signed distance functions (SDF). In boundary representations (BRep), objects are defined by vertices connected by edges and faces. In function representations (FRep), objects are defined by a function f that maps any point (x,y,z) to a real value d, the distance to the objects: f(x,y,z)=d The components are organized in groups. A typical workflow is to choose objects from PRIMITIVES, combine them using e.g. Boolean operations from COMBINATIONS, add further MODIFICATIONS as necessary and finally visualize the distance object using a component from the MESHING tab. Furthermore, there are different kinds of LATTICES, some MATH functions, components to convert Rhino GEOMETRY into an SDF and some utilities to ANALYSE the SDF.

Who would have thunk it? Is everything being reduced to some sort of modeling software?

Dr. Mathias Bernhard



Dr. Mathias Bernhard is a Research Associate at PSL. He was a postdoctoral researcher at the Weitzman School of Design, University of Pennsylvania. Before that, he was a postdoc at Digital Building Technologies, ETH Zurich. He holds a Doctor of Sciences (Dr. sc.) in Architecture from ETH Zurich. His thesis, “Domain Transforms in Architecture – Encoding and Decoding of Cultural Artefacts,” draws a map of the variegated field of CAD and investigates the implications of alternative models of abstraction and their creative potential. He is an architect with a profound specialization in computational design, digital fabrication, and information technology. He is particularly interested in how artifacts can be encoded, made machine-readable, and digitally operational. His research focuses on what computational design instruments can fully harvest the potential of recent developments in digital fabrication, more specifically, additive manufacturing. He is the developer of various volumetric modeling packages that employ function representation and signed distance fields as an alternative to the more widely known boundary representation for three-dimensional geometry.

2020 winner for “Banknote of the Year” . . .

Mexico’s 100 Peso GUARDIAN™ Polymer Banknote Wins ‘Banknote of the Year’ Award

Mexico’s new 100 peso GUARDIANTM polymer bill has beaten more than 100 other candidates to win the prestigious “Banknote of the Year Award” for 2020, awarded by the International Bank Note Society (IBNS).

The new 100 peso banknote is the latest in a long line of polymer banknotes issued by the Mexican central bank. The first – a 20 peso note – was unveiled in September 2002, with a redesigned note issued 5 years later. The series will also feature 20 peso and 50 peso notes to be issued later. Once the latest ‘G Series’ of notes is complete, the bank estimates that polymer will be used in around 2 billion notes in circulation in the country. This represents around 30% of the total volume of notes in circulation.

Banco de México was both the printer and issuer of the award-winning design banknote. The vertical format note is printed on CCL Secure’s world-leading GUARDIAN polymer, which is currently used for more than 170 denominations and 75 billion banknotes issued by over 25 countries.

The award-winning note features one of Mexico’s national heroines, the writer Sor Juana Inés de la Cruz. The reverse “piece de resistance” image features the Monarch Butterfly Biosphere Reserve, a renowned temperate forest ecosystem. The design continues to highlight Mexican cultural and historic characteristics with new graphic motifs. The banknote also features significantly improved security features as part of the transition to GUARDIAN. Polymer banknotes continue to be popular IBNS favourites.

From all significant newly designed and widely circulated banknotes released in 2020, the 2000 members of IBNS nominated notes from 22 different countries, drawn from 5 continents – Africa, Asia, Australia, Europe, and South America – as well as Central America, three island nations, and the Middle East.

Polymer is always popular with IBNS members, and Mexico’s award-winning entry is seen as providing a template as other countries reconsider how they design and promote new banknotes.

CCL Secure’s Director of R&D, Marketing and Design, Dr. Tim Berridge, commented: “Naturally, we’re delighted that Banco de México’s new 100 peso GUARDIAN polymer banknote has won this award. Such an innovative and beautifully designed banknote is a testament to the Bank. It’s also recognition of all hard work and support provided the CCL Secure team based at our production facilities in Queretaro and our design team in Melbourne. They helped to bring the Bank’s design concepts to stunning reality.”

As well as operating GUARDIAN polymer production facilities at Queretaro in Mexico, which form the basis of a longstanding relationship with Banco de Mexico, CCL Secure recently opened a purpose-built recycling centre in Zacapu, in the Mexican state of Michoacán. As with all GUARDIAN polymer banknotes, the new 100 peso note starts life as polymer pellets which are then transformed into the GUARDIAN polymer substrate film. Once the banknotes have completed their working life, they can be recycled by turning them back into polymer pellets. These are used for a wide range of products, including outdoor furniture and building materials.

Powerful Security Features

The unique manufacturing process that creates GUARDIAN™ polymer banknotes makes them inherently more secure than paper alternatives. In addition, CCL Secure has created and developed a range of additional security features to provide even higher barriers to counterfeiters. Our team is constantly researching new innovations and technologies. Sign up to our newsletter for regular updates.


CINEMA is a stunning and memorable feature that provides depth and movement. The sheer complexity of its construction – with GUARDIAN at its core – inhibits counterfeiting and provides a secure store of value. Read more about CINEMA here.


This Optically Variable Device (OVD) reveals a hidden image when a light source is shone though the GUARDIAN window. ECLIPSE is a highly secure level 2 feature for the public and retailers.


VIVID is a family of level 2 security features that enables fluorescent and IR authentication to be integrated with the substrate design.


G-SWITCH is a visually overt feature that helps to create public confidence in billions of banknotes around the world. The easy to detect feature changes colour when tilted or when viewed in reflection and transmission.


AURORA uses the colour switch effect of two inks that have the unique effect of being similar in reflection but differ when viewed in transmission. This gives the public a fast and efficient method of authentication.


METALIX provides a metallic sheen in a range of colours adding to the impact of an image within the design, as well as offering exceptional durability.


CAMEO uses the GUARDIAN window and is a complex, secure and intuitive feature that can be viewed in reflection, transmission and on both sides of the banknote.


VIGNETTE is an effective alternative to a multi-tonal, mould-made water mark, that is visible in reflection and transmission.

Building Resilient Circular Economy

Circulor’s traceability solution will permit Recycling Technologies and TotalEnergies to track the recycled plastic waste and confirm compliance with predefined manufacturing parameters, such as elapsed time, mass balance calculations, responsible sourcing standards, or energy usage.

The industrial partnership is supported by the UK government’s innovation agency Innovate UK., with expectations that the novel technology will ensure transparency over the origin and the quality of materials entering and exiting recycling and manufacturing facilities.

The ultimate goal of the TrackCycle project is to link plastic waste suppliers, plastic recyclers, polymer manufacturers, and consumer goods companies together into a closed-loop plastic waste recycling ecosystem.

My guess is that polymer currency is already blockchain-enabled, so they get their blockchain either way…

Of course the first thing that comes to mind is nano polymers - getting us ready for piezo-wearable “currency” maybe?,-harvesting%20and%20-storage%20devices.
