Literate documents

The extensions explained with their code, drawn as X_eTaL draws it, and the results it gives.

Blender: arrays to video

• Matrix multiply, arrays to video -- one product a step at a time, then 134 million of them as a fly-through, from X_eTaL arrays to Python to Blender to an MP4
• ReLU and softmax, arrays to video -- a tiny network's last steps, from X_eTaL arrays to Python to Blender to an MP4, with no hand-written Python

Voxels

• Water that drains -- a lake on a voxel hill, emptied a layer at a time, by moving cups of water

Elsewhere

• X_eTaL's literate documents -- the language itself: a beginner's start, a tour, libraries, classics
