I didn't know what the compiz-fusion was, so I did a search and saw a youtube demo. Sure enough, lots of deforming cubes, and rotation and fancy effects. One thing I didn't get is, why? How does that help anything? OK, the geek in me loves the graphics, especially having done graphic programming before, but one of my loves is user interfaces and I didn't see anything in all of the compiz fusion demos that made the user interface better to use, or friendlier, or any more obvious. I watched the windows zooming round, and my thoughts went back to talking my mum through trying to download a scanner driver from the web. I am glad my mum doesn't have that!
