OK...I got some crap for you to download and try. Unzip to any directory and make the html file your background. (I did NOT create these codes, I just implemented them into HTML docs.)
1) Alien. It will make your background space-like and an alien will float randomly around your desktop.
2) Space. It will simulate space travel, making your desktop "fly through space".
3) BGScroll. It takes any image you want (replace image included with image of SAME NAME AND EXTENSION) and scrolls it vertically on your desktop.
Two links to ones I will implement if I am requested to (I am up at 11:40PM, I'm tired).
1)
Color Cube= click a color on the cube displayed to change your background to that color.
2)
Matrix= Makes Matrix-style digital rain on your desktop.
OPINIONS PLEASE. I know I did not make these codes myself, but I put them in a format you can use as your desktop background.
If you need explanations of Javascript or HTML, ask Fyber, not me. Fyber likes to type.
Now I'm tired. ZZZZZZZZZzzzzzzzzzzz......
