Funny that this appears now, because I recently decided that I'd like to get back into ASCII art by making ASCII art shrimp. Of course, they are less detailed and smaller in size than much of the artwork here, but that's part of the fun. I started by asking a few people on tilde.town if they'd like to add any and fairly quickly I had a decent collection.

You can see them at http://tilde.town/~owenversteeg/. If you have any to add, please let me know and I'll put them up!
