NerdPax! is a full html5 / Canvas web drawing surface developped by Lorenzo Pastrana.
The NerdPax! web drawing surface has been designed to stay as simple as possible. The look and feel has been accurately tuned to stay near analogic when a Pen Tablet is used
A calligraphic orientation has directed the overall developpement so far, but a "wet" brush and a "crayon" tool are also available as well as the unavoidable scribbler tool.
Each tool has been given a lively and fluid dynamics management.
NerdPax! is to be augmented with a sharing and diffusion platform for users work, and will be connected to the social / sharing APIs (Google+,Twitter,Facebook) and the pictures galleries APIs (Picassa,Flickr).
A touch interface version is to come, it will come with a simplified UI but will keep the brushes dynamics unaltered.
Most of the developpement took place on Chrome which has proven the best performance and graphical restuls so far, Firefox and Safari are also compatibles.
