Bumptop is a really cool 3-D desktop that totally changes the way you handle files. I also like the way SkyOS handles file management, execution, and searching but Bumptop is just cool and it doesn't require typing or guessing alphabetically to find things. It would be very cool if SkyOS offered Bumptop as an alternative to their already amazing OS! 

Considering I haven't used Bumptop I can't really say much more about it, but it is something I find really interesting, because I am a very visual person, and I would love a more visual desktop for handling files and such. There is a You Tube video I watched awhile back that shows it in action, which is here .
