My first attempt at using the HTML 5 Canvas

Today I found myself wondering what kind of performance I can get with Javascript and the new HTML 5 Canvas. Looking for something fun to implement quickly I dug up some code for a demo I did of the Silverlight WriteableBitmap and started porting that to Javascript.

Now I am not much of a Javascript guy, in fact I can safely say that this is probably the most Javascript I have written, probably more than all other previous attempts at playing with Javascript put together.

So why am I writing about this if I lack so much experience, well to be honest, it is because I was actually quite surprised by the results and I thought it would be worth sharing.

I did the initial development using IE 9, and I was impressed by the performance, I hit the test page using Firefox 7, Google Chrome 14 and Safari 5.1. By far Firefox was the slowest, IE 9, Chrome and Safari all performed really well on my Window 7 box. So if you are viewing this in Firefox, try it with IE 9 and see if your experience is similar.
