Been wanting to play with this for a while now. It’s a lot of fun, in an old school, AS1 type of way. I have a lot to learn, but was able to whip this up in an hour or so. Once you figure out how to get at the canvas and the context, it’s all pretty straightforward. Just like AS3, without the data types. Or classes. Or display list.
Use your mouse to click on this underlined text to see Canvas awesomeness.
No idea what browsers this might or might not work with. It does work with Chrome and IE9. Haven’t tested beyond that.
I’ll probably re-do some more of my old AS1 experiments, just go get a feel for things.
Oh, and though it should be obvious how to find it, the JS source for this is here.
