This is a demonstration of the alpha version of CompComm (a temporary name) which is a result of the re-merge of Beryl and Compiz. These plug-ins and effects are bleeding edge and are not expected to work perfectly. However you CAN try them out. There are instructions for Ubuntu Feisty on forums.opencompositing.com Take a look at the first generation videos of Beryl + Compiz works (AKA Vista’s Demise) here if you haven’t seen it yet.
