Elive
Elive old stable has 3D effects without need of an accelerated graphic card (though is suggested), thanks tot he integration between E17 and Compiz (Ecomorph). The Beta version supports the newest linux kernel and is available both for i686 and amd64 architectures, though it drops the support to E17 (not compatible with the latest Debian Stable release) in favor of E16, which, despite being older, is way more stable and well supported by modern distributions. It is fairly easy to upgrade to E23, which is considered the future Desktop Environment of this OS.
