Live CD for PPC?

An anonymous reader writes "After reading this article, I was pretty excited about trying an Ubuntu live CD on my Mac, because I've heard a lot about the distro. But it turns out the only live CD is for x86. Looking around for PPC live CD's that support modern hardware (like a G5) and demo modern versions of KDE and Gnome has proven fruitless so far. Does Slashdot know of any current projects that have released or are working on releasing a nice PPC live CD?"
