Ripped right off their homepage: In a recent Slashdot article, someone asked if it were possible to create a fully-featured bootable Linux LiveCD for the Macintosh. We thought this was a great idea. So today, we are releasing two full-featured LiveCDs for the PowerPC: one with KDE 3, and another with GNOME 2. Take a look at the KDE LiveCD running MacOS X in a window via Mac on Linux. LiveCDs can be downloaded or from several mirrors."
