MorphOS: Amiga operating system meets PowerPC Macs
 

Low End Mac's Sebastian Patten takes a look at MorphOS 3. "MorphOS is for Amiga users. Period. And it's for those Macintosh users who like to experiment and experience a new operating system on their PowerPC Macs. That's where I see myself, and I had a lot of fun playing around with MorphOS on my eMac. It is not a full OS X replacement, but it can come close to it, depending on your computer needs."
