The Creative Process back to square 1 for the 5th time!

I am trying to create something that is different from everything else out there (or as far out there as I can get, and hopefully beyond even that!) So for the about 5th time my pal and I are back at square 1. At first I was happy with the ideas we had. but as I look back on them they were pretty much done before. So back to the drawing board... sweet!
