I really like this effect. Simple and to the point. I used a background image with a transparency of 50% which makes it able to pass some of the background color thru.

I rotate the background color from black to dark red to a deep orange to a dark green ... this makes the page a bit more interesting, a feeling of motion.

The text window has custom borders I made, just a rectangle image with a greenish gold border, burred into the black background, then made 50% semi-transparent.
