Generate pixel graphics for the Tidbyt

Indiepixel

Contributions more than welcome!

Basically… pixlet in Python.

Why?

This is an example for generating images for the Tidbyt device, a nice LED display. The company that made the Tidbyt got acquihired and won't be developing the software much in the future.

Pixlet was very convenient, but is an oddball for a tech stack: implemented in Go for people to consume in Starlark. Starlark is a niche language. It'd be nice to support a mainstream language.

This is a WIP implementation of the same concepts as pixlet in Python.
