Groovandra
At a riptano Cassandra training in NY, Jonathan Ellis showed us twissandra and pycassa. I confess to never really using python before, but I found interactive python rather amazing.
So at that point I decided I needed two things:

A nifty confluent interactive cassandra cli alternative
Groovandra is still new (and open to suggestions) but it does work, so
have fun.
