The developer's site says only for the Pearl, but you can take the gamble and see what happens if you install it on the 8800. Or e-mail the maker and ask about it.

As to changing the color, it's just something new and different than the same ol' white color.

Also, during the night I did a test, the trackball is now so bright it acts as a flashlight.

And lastly, when in a crowd that ball will now scream "Look at me, I am cool and you are not."
