Making a new post because I ran out of time for edits:
Ability to write our own shaders for filters.

Some potentially fun variables to expose to the shaders:

Elapsed time variable (based on current frame in animation and fps)

Position delta since last frame

Stick figure properties such as size, rotation, color, and scale

Absolute position on the canvas

Node data (the figure’s node data for that particular frame)

Random seed for introducing randomness in effects while ensuring they are repeatable across frames.

Audio data (sound effect volume and pan for that particular frame)
