Split the rain pass's compute shader in two, with one governing brightness and the other governing glyph cycling. This allows glyphs to randomly cycle properly, and leaves room to store new properties.

 TODO:
 
-Random cycling should actually be random
-  Compute shader should have separate channels for cycle and symbol
+Update WebGPU
+  Compute shine and symbol in separate methods of compute shader
 
-Try to identify cursors more consistently
+Reformulate the basis
+  https://buf.com/films/the-matrix-resurrections
+  Base cursors and other colors on BUF clip
+    Show this stuff for showComputationTexture
+    Pixel grill?
+  Tune the colors
+  Maybe glow can be an SDF-derived effect instead, look into it
+
+  Migrate the rest of the project over
+  Migrate WebGPU
