Hey remi i did the same thing as you did only with the 4 side cube. Did you manage to succeed in setting some icons and other stuff for the cube?
What did you use for it? on of the apps or just registry hacking? if registry what did you set where?
even my old applauncher icon's have dissappeared now. and i think they are still set....???
[edit]
Never mind, already found what i needed to change
