This is a simple demo to test the functionality of Canvas in HTML5. If your browser support Canvas, then it should show you some colored scrolling bars on the background of this page. The color should blend between different tints and the angle of the bars should change slightly over time. I hope you are not experiencing any performance problems, because this background is a little bit heavy on CPU usage.
More information about this page and how I have implemented it, can be found at radikalFX.
