In a recent Slashdot article (and an OSNews one), someone asked if it were possible to create a fully-featured bootable Linux LiveCD for the Macintosh. Gentoo thought this was a great idea. So today, they are releasing two full-featured LiveCDs for the PowerPC: one with KDE 3, and another with GNOME 2. Screenshots here and here. To use the LiveCDs, simply boot one on your “new world” PowerPC (by pressing “C” during the machine bootup).
