I'm testing it out on my GNOME 2.5 installation. It rocks pretty much :-D. I wish the StarterBar that pycage created would autogenerate a few things (like the "normal" GNOME menus/starter bar does) but it still is really cool. Note the badass tranasparency. Also, you cant see it below but the icons on that bar along the right magnify when the cursor is over them.
I should admit right now I'm jealous of MacOSX's look. Hehe.
Update: Nobody who reads this (as few as it is) really gives a damn, do they? Hehe, once again alienating my meager "reader base."
Update Deux: It should noted for clarity that gDesklets is the program controlling the cool transparent bits over along the right and top right of the screenshot. gDesklets is written in Python with a tidbit of C.
