I was going to mention more stuff but I kind of fell asleep. Anyway, if you have a preferred terminal you want to run I am sure there is some way to bind its execution to a button and make it act similarly with enough regular expression magic in Compiz and CCSM.
While I like Terminator for its utility and capability to be like tmux without tmux, you may like Terminology for its fancy effects. Or you could be stupid-bonkers like me and try to get zsh with a fancy theme to load up in fbterm at a local shell session for giggles*.
*: ...Which really isn't that bonkers in hindsight, as you can define how many characters appear by changing fbterm's font size rather easily and zsh is stupid powerful, but no common user needs their text-only environment to do that much.
