Ringtone Randomizer

[dirtypirate]

Okay, I don't know if this exists yet, but I'd like a program or tool that will allow me to set my ringtones to be randomly select when the phone rings. I've downloaded about 50 ringers and I think it would be a little more enjoyable to have different tones throughout the day when the phone does go off?

Anyone know of anything like this? Can anyone make this?

Thanks in advance!
