How Java supposed to look like on OS X

Quaqua is open source UI java library for OS X. Subjectively, IMO, it looks better than Swing and feels native on OS X.

I don’t know about how useful Bumptop user interface is, but for sure it’s cool looking.

From their forum, it seems like Bumptop only works on Windows.
