The typical Chinese sources have been selling "digital hourglass" type ornaments that work like this for a while. There was a whole game based on this sort of thing back on the Acorn Archimedes: Cataclysm https://www.youtube.com/watch?v=3Byyz1Vlv8w It got remade for the 360, but the original was regarded at the time as surprisingly impressive for the machines it was running on.
Instead of a business card, I'd love an ultrathin pleasure card you can refill with virtual beer and virtually drink! You could input your weight, and it could track you BAC! I made "PalmJoint", a beamable Palm pleasure card for CodeCon 2002, when everybody was beaming their contacts around by IR at conferences, I would beam an interactive doobie simulator a bunch of people could play together in a circle. Each perso…
Ha! That's pretty cool. My first thought with this card was that it could be "gamified" into something that kids would probably love. A clique-y, social thing where kids could "pour" some of their fluid into another's card, with NFC or something. User preference colors that don't change when "poured" could help indicate how many different people have interacted with your card. But enough spitballing. There's no kille…
Remember those little LCD cube block toys with the stick dudes that lived in 'em, then when you plug 'em together they interact? Those were the days.

Liquid Pokemon Eggs and Sperm! Gotta catch it all! Then you can lay the fertilized eggs at any GPS coordinate to gestate and hatch later on. That could start a whole genre of AI (Artificial Insemination) Life Simulation games.
Off topic, but where should one start learning writing physical simulation? Several years ago I ran into this project [0] and got overwhelmed even the algorithm can be written in 88 lines of C++. I realized that out of all CS topics, physical simulation is probably the one I knew the less (not saying I'm a compiler/database expert or something, but at least I've implemented a toy compiler and some basic data structur…
I'll give you a simple example. For diffusion of heat between 2 points, the rate of change (first derivative) is proportional to the difference in temp between them. So you make an update rule for points on a grid that says "calc the average difference of a cell's temp with that of its neighbors, multiply by some constant, and that is the amount to update this cell at this time. Run that for every cell in parallel, many times." Then you tack on a visualization and you can watch the heat diffuse. A fun example would be the cooling of the proto-Earth. You can watch the crust form.
Heat diffusion is a good starter problem. So is gravitational interaction.

But with supports along the sides that could solder one the top and/or bottom of the PCB. You'd have a notch cut out for the connector.
Amazing project, but the font on the back of the card is gross.
That’s cred, man. Real cred. Wack font. Circuits exposed. Pixels with fat borders between them. An ugly charging port. But more stuff, packed into a small sleek volume than reasonably possible. Working perfectly. That’s not Jobs. Oh, no. It’s effing Woz. The guy is a true hardware engineer.

Electronics can be surprisingly easy and cheap to build these days. He designed the circuit and layout with software called KiCAD (free and open source) then submitted the designs to a fabrication house - probably a popular offshore one - that easily can handle that level of board and component placement complexity. It would probably cost only a few hundred to build and ship, with 1 month turnaround time. You can als…
As long as there aren't surprise 50% tariffs.
It would be cool to have a USB C connector that goes through the PCB so total height is that of the connector and not board+connector.

rather it's even smaller, it simply has the inner part of a usb c connector - exactly the thickness of the pcb
