Generate psychedelic background images
If you like variation in your desktop backgrounds and you're into a bit of 60's psychedelia, then you should take a look at Google's Top Draw. This free program automatically generates desktop backgrounds using Javascript and the Mac paint palette, resulting in endless combinations and stunning images.
Top Draw offers two modes: The Editor and The Menubar Viewer. The Editor is for those who know how to program Javascript in Terminal, while The Menubar Viewer is for those who simply want to enjoy beautiful pictures. In The Menubar Viewer, you have some control over the display of the backgrounds, including color using the palette and the shapes of the design (rectangles, circles, squares, etc.).
One of the great features of Top Draw is that every design is unique, and you can let it automatically cycle through backgrounds, ensuring that every time you revert to your desktop, you get a completely new and one-of-a-kind design. Top Draw exemplifies Google's characteristic neatness, lightweight design, and impressive uniqueness in the backgrounds it creates.
