It has been discussed and there are several proposals on http://issues.apache.org/jira/browse/CASSANDRA-231
I personally like a few of them.  We're still looking for some direction or perhaps a vote -- chime in if you're interested.

Just out of curiosity, what's the status of Cassandra having an official logo/mascot? I understand this is perhaps not a high-priority issue right now, but again I'm curious where this stands. Has it been previously discussed or is the project taking ideas/suggestions?
