Literally Canvas is an extensible, open source (BSD-licensed), HTML5 drawing widget. It depends on jQuery.
You can draw, erase, set the color with the eyedropper, undo, redo, pan, and zoom. A semi-stable API allows you to add your own tools. It works great on mobile devices.
It’s easy to get a data URL for upload to a site like Imgur or load/save a user’s drawing.

We would be excited to see contributions of any form. New brushes, optimizations, feature requests, use cases, designs, bug reports – you name it, we want it! Just head on over to GitHub and get started.
One particular area where we’d like some help is in styling the toolbar. If glitzy CSS-based UI is your thing, we’d love to hear your suggestions or merge your pull requests.
