This is what happens when I get bored at midnight during Christmas break and don't really want to think about anything. I could be trying to forget Kenny from South Park again, too.
X-Chromium was made in Photoshop 7 on my mac in about 15 minutes. There is one colored layer in the entire image. Other than that, it's all stock gradients (well, save the logo) and interesting layer modes. It's pretty amazing what you can do with layer modes and colored images.
I made a second version on March 21st, 2003. It is very close to the original, but not quite the same. The advantage is that I can render it at any size, including poster sizes. So you can buy posters now too. Expect changes coming.
