Real-time webcam effects built with openFrameworks. Effects work as coordinate remappers — like analog modular synthesis. Patching a set of transformations together generates a visual result.

Effects

Key	Effect	Params
1	Wave — sinusoidal pixel displacement	—
2	RGB Split — per-channel horizontal offset (chromatic aberration)	—
3	Slitscan — each column samples a different past frame	q/a depth
4	Block Displace — grid-based spatial distortion	w/s size · e/d amount

Multiple effects can be active at once and apply in order.

ASCII Renderer

Key	Action
5	Toggle ASCII renderer
6	Cycle color mode: mono (green) → row-tinted → per-char
m / n	Cell size smaller / larger
, / .	Cycle char sets: standard · sparse · dense · organic

The ASCII renderer reads from the same processed buffer as the texture renderer and draws on top of it.

Requires openFrameworks 0.12.x on macOS.
