Open-source web canvas
A fully open-source creative canvas for the web. Brushes, sketched shapes, text, and pictures, with room for whatever you want to make.

A dozen brushes. Color, width, line style, shadow, and the other custom settings can all be changed.
Built-in sketched shapes, fonts, and pictures, with a wide set of custom settings.
Move, scale, and rotate anything you draw, and set its layer, opacity, and lock.
Paint Board can hold several boards on the same page, enough for a wider range of work.
