ColorWall is a minimal implementation of the visualizer part of the allegro project (https://github.com/vishnubob/allegro).
ColorWall is a simple framework for implementing and displaying effects for a wall of pixels. To add a new effect, create a class in effects.py inheriting from Effect and implement the run() method. Add the new effect to the Effects list at the bottom of the file. ColorWall comes with a few example effects.
Watch an example ColorWall at http://vimeo.com/16522975.
ColorWall's pixels speak HSV (http://en.wikipedia.org/wiki/HSL_and_HSV).
Tkinter, a GUI-programming toolkit for Python: http://wiki.python.org/moin/TkInter
To see if you have Tkinter installed, at a Python prompt run:
import Tkinter
To run the ColorWall:
python run.py
This will run your effects on the default 8x8 pixel wall. To change the width and height of the wall, pass the -w and -t options, e.g.:
python run.py -w 5 -t 10
To run only specific effects, pass the effect names on the commandline. e.g.:
python run.py Rainbow Twinkle KnightMoves
