Pixel Pointillism is a camera-based web app about the phenomenon of optical mixing.

Pixel Pointillism is a web app that converts the user’s camera feed into eight component colors through dithering. The user can save the dithered image or download an instruction grid for making a pointillist painting of themselves.

The project started as a teaching tool for middle school students when I was a teacher at Hwa Chong Institution. The phenomenon of optical mixing is not straightforward and Pixel Pointillism helps people learn the concept by creating an artwork of themselves.
