I just think they're neat

I love it! The “3D” demo is particularly impressive. Can you do something with just a single line? I’m thinking of a GPU-accelerated status line animation.

This is really awesome. Nice work!

Curious if you can get away with Burgers on a CPU: https://youtu.be/oxzfY-hPt2k

Are they very different in terms of compute? Looks like Burgers saves maybe a couple of FMA per cell. I’m pretty sure you can get away with Navier Stokes on a CPU. (Depends on the resolution, of course, but the examples here are relatively low res.)
