[CentOS] installing 3d desktop centos 4.4

I have a piii 550 with about 256Mb ram with an agp 32Mb video card and Im
wanting to install a desktop that has the 3d cube on the screen and use
the arrow keys to select wich desktop you want to use and it brings it to
the screen.
 Has anyone heard of such or tried this??
Thanks
