Looks great. Would be interesting to add to blogging software to allow a quick sketch to be added to a post.

How would you go about persisting the canvas? json encoded output?

I don't have my phone with me right now. Can anybody confirm if this works on iOS? I'm asking because I'm looking for an HTML5 drawing script which works on mobile browsers.

Yep. Pretty snappy in iOS7 at least.

Remark: The download results in an extension-less format. Which format is it?

Thanks! By default the base64 string of the canvas image is stored in session storage to make the canvas persistent.

First thing I thought of with this was creating a mobile app that would be a cloud based instant note taking tool. Preferably used with a stylus.
