Thanks Jackalo. The new PearPC SDL builds has been published at Richard Goodwin"s web site. This new release comes with the Win32 clock patch which smoothens a lot of graphical task, such as the Genie Effects in OSX. If I understand this correctly, I would imagine that this is not the official release but it was based from the official pre 0.3 tree.
PearPC is a software that let you emulate the PowerPC architecture thus making it possible for you to run OSX on PCs. Keep in mind though, that the CPU emulation speed is nowhere near the production level of use.
Anyway, if you would like to give this a go, click at the links below!
