Boston Python Workshop/Saturday/ColorWall
The ColorWall is a framework for implementing and displaying effects for a wall of pixels. During the Saturday workshop, you will write your own effects for the ColorWall.
Layout
The ColorWall code consists of 3 files:
run.py: take arguments from your environment (like a specified width and height for the wall), set up the wall and effects, and run it.wall.py: the logic behind the matrix of squares that make up the wall. This file has a comment block at the top that summarize the interface that you will use when programming your own effects.effects.py: where effects live. This is the main file that you'll be editing during the workshop.

- The ColorWall uses the HSV color space. Wikipedia has a complicated explanation for what that means, but what it boils down to for the purposes of our project is this: each pixel gets 3 values: hue (e.g. am I red, green, or blue), saturation (am I pale or intense), and value (am I bright or dark).
effects.pyhas example effects that exercise hue, saturation, and value independently.
