Has anyone been able to do much with the <canvas> element? I'm going to be working on an internal webapp with rails and I'd like to have a section where someone could draw, with their mouse, anything in a fixed-size box. I'd then like to save what they drew as an image (to a database) to be used as the image for the content on that page. I found a tutorial on how to draw over a page, and I've found many that let you put in a preset image within the <canvas> elements, but nothing that lets you save the drawing as a .jpg or .gif and use it later. And I'd like to be able to edit the drawing as well. I know it won't work on all browsers (IE), but being an internal app I can control what browsers are used so this isnt an issue.
