Yesterday, I installed Ubuntu Jaunty (soon to be Ubuntu 9.04) on my desktop, after I accidentally erased my hard drive by dd’ing an image to /dev/sda, when I meant to dd it to /dev/sda3.
I tested 3D, and I got this interesting effect when running glxgears with compositing support enabled:

glxgears seems to be transparent. Don’t know what the purpose of it is, but it looks kind of pretty. Although not as useful as cairo-clock, which has been around for yonks.
