+- render - GPU rendering of a signed distance function.
+- physics - (TODO) physics demo (either flows or N replicated double pendulums)
+- transformer - (TODO) a neural network transformer block computation
+- autograd - (TODO) toy autograd
 - webgpu_intro - A minimal from-scratch example of how to use WebGPU directly
   without this library. This is useful to understand the code internals of
   gpu.cpp.
