The fluid simulation logic is split into a separate crate.

This is why my first prototype had a white border around it. The LEDs were red back then, so I don't know exactly what I was thinking, but I was aware of the problem.

Thanks for all the help. I'll be ordering this soon and I'll be sure to post it.

Is this any better? I hid the vias

Ok, for real though, can someone just tell me what font to use? We can all see this isn't my strong suit and now you're in my head.

I was thinking of throwing in a game like Tetris with just accelerometer controls. That'll be after I find a job though. Numbers were actually the first things I displayed, I actually still have all the code to display them still sitting unused.

Text has been less of a success. Having the letters be easily legible takes more space than I would have thought, and the small pixel fonts don't look great with the big spacing between the LEDs. Maybe some scrolling text would look good, but I haven't focused on it too much. I tried getting a QR code displayed, but it didn't want to scan.

For buttons, I'm kind of married to the idea of no buttons. The accelerometer does recognize clicks and double clicks in different directions, so that might be useful for something.

I encourage anyone who wants to fork/contribute/post issues on this to do so and I'll try to be a good maintainer.

I tried, that's why it's 21x21. Still haven't managed to get it to read.

That's actually not the same guy. He made the pendant that this project is based on.

Indeed, JLC for this one, though I did start off by hand assembling the first version with a 3D printed jig to locate the LEDs.

The render is pretty gnarly, but it's not quite that bad in person
