This is a lightly modified version of the harmony sketching application created by Ricardo Cabello. It adds a color picker for setting stroke and fill colors. http://mrdoob.com/projects/harmony/ Harmony uses the MIT license: http://www.opensource.org/licenses/mit-license.php It uses a preview release of YUI 3.1.0 to pull in the YUI 2.8.0 colorpicker, delivered via the Yahoo! CDN. It allows you to colorize the stroke style for all of the brushes except 'chrome', and allows you to set the fill color for the 'boxes' brush. Some things that would make this even more interesting: * sliders to specify transparency settings * undo * blend * erase
