It turns out finding old Sowndflower releases for PowerPC was a royal pain in the arse. I had to get them from the wayback machines's backup of the old Google Code archive (which is now down). I figured others may want an easier place to find them so I put the two versions that work with Tiger and Leopard on the garden. I hope someone finds it useful.
