To be frank about it, there aren't really any Mac themers doing anything that's different to the whole minimalist thing that's popular nowadays on Windows.(Not to mention all the good Mac themes have already been ported/plagarised) It stems from Msstyles and OSX windows being essentially non-freeform, so the people themeing stick to the standard no-frills layout on both OS'.
David Lanham and Bill Bart are the only two doing anything unique, and I'd love to see both of them try their hand with Windows skinning.
