The Champion Sound homepage, designed by Matt Lackey and built by myself for digital-telepathy is a mass of overlapping gradients and transparent PNGs.

Definitely one of our [Lackey and I] more visually appealing projects together and also the loudest! Below is a short video showing the homepage slider and the features page:
