Got bored tonight and decided to [url="http://jsfiddle.net"]fiddle[/url] around, picking the HTML5 Canvas as my victim. I decided to create an infinitely-scrolling rainbow thing (random-number based) and, well... This is the result < http://jsfiddle.net/n8XJx/ >.
Not sure what to say, but a couple of my friends thought it looked pretty spiffy. Figured I'd post it here; maybe it'll help someone or maybe someone'll have suggestions on how to optimize canvas usage?
