A friend from work played with setting up XGL on his ThinkPad this evening. Wow… I’d heard it was nice, but…. wow.
For those who’ve not heard of it, it’s a 3-D X server architecture. And for those to whom that makes no sense at all, it gives you a 3D graphical desktop environment – instead of your normal flat ‘desktop’.
That really doesn’t do enough to sell it. Take a look for yourself. Or better yet, give it a try!
