I've just tested deviantART muro , but I can't actually input any lines into it... Sketch in 3D With Animating Lines on HTML5 canvas , however, does work! It's too slow to consider attempting a full drawing in, but I'm now wondering if there are any other interesting HTML5 (maybe even Java..? I doubt the Eee Note has a Java plugin) programs I haven't thought of... Particularly, if there are any HTML5 programs that can allow sketching with extra functionality, more organised note-taking, or interaction with PDFs... any ideas?
