Thanks for all your new entries. Many of these are excellent, although only #78 depicts a conch shell. (However, #79 and #81 could be the front of a shell.)
The only problem with #78 is that I keep thinking it is a bee. It would be best to have the image clearly look like a conch shell that one can blow through.
Basically, the conch shell in Manoga is going to be like the bird in Twitter. It has symbolic meaning for the function of the site.
Regarding #82, #83, #84, #85, and #86, they are all great designs. However, they depict a nautilus shell. If we can get a conch shell that looks as cool as those nautilus shells, that would be amazing.
Thanks again for your excellent submissions!
