"random" logofile

[sticklerm3]

So, I have a few different logo files I've come up with, random symbols for things that i like, was wondering if there was a way to have a few logofiles and have the script randomly choose one each time its launched, or maybe even dependant on an environment?

Heres an example of the Anjunabeats logo i made, i did another one of a band that i thik would be cool to rotate between!
