Building off of mixophrygian's original "Etcha-sketch" web app, I thought I'd try to make it even more awesome because reasons.
- Completely redesigned interface and color scheme
- Updated to HTML5
- Refactored jQuery
- Change grid width/height
- Change square count from main interface
- Click to draw by default (with "clickless" mode still available)
- Rainbow color mode
- Colorpicker tool
- Save your image to BMP, GIF, JPG, PNG
Thanks to Mads Stoumann for the help on making a ruler, and jQuery.Transit for positioning it.
