How does the cube work?
Just like in the complete cube you can click a button to try a new background color - the RGB code will be shown in the status window.
The squares without a button don't give any new background color. They contain gif tiles to be used as downloadable background graphics. The status window shows the code for the browser-safe colors they sit between. (If you do click them, you'll go to the default-button.)
(Here is an "I want it fast"-version of the tiles!)
Try to go to the top of the page and reload it if a button seems to disappear.
Click the default button to get the default color back.
