# Noton

A minimal [color computing playground](https://wiki.xxiivv.com/site/noton.html), written in ANSI C.
A [color computing playground](https://wiki.xxiivv.com/site/noton.html), written in ANSI C.

Right-click to add nodes, and left-click to add wires. Nodes will emit a positive signal if all the connected wires have the same polarity. The screen has timers to the left, and notes to the right. The default timers are 6 trackers, 4 sequencers and 2 pools.
