Lots of lots of guitar tuning threads on Mudcat, Mr Happy. Have you exhausted them all? If so, wow.
One of my favourite guitarists, Bruce Cockburn, employs some very unusual tunings, and you will find them on various websites if you're interested enough to search them out. They include (low to high) DACGCF and CGDEGC.
Sometimes he'll use the tuning EADGBE - now that *is* weird.
