Working with a canvas
Start by downloading a
that sets up, for the HTML5
a web page that corresponds to the
Mozilla Developer Network Canvas tutorial, but in a format

Don’t go overboard here and do experiment.
My suggestion is that you go to the Drawing shapes section and modify some of the figures there. For example, make the smiley face frown.
If you want a real challenge, you can try out some Basic animations, Be aware the jslint may scream after every cut-and-paste.
