Thanks alot for your great contributions! #109 and #108 are the two closest to what we envision for our logo. Entries #103 - 107 have a good typo, but the graphics are catching too much attention. The typo should be dominant.
I like the concept with the keys (#117) very much! The way they are intercrossed is very classy. What sort of different, ancient-looking keys could you inorporate as alternatives?
