I acctually have my own personal sig replaced by the output of a php function. i have fun by adding things like the readers username into my sig, it got alot of members really paranoid until they figured it out

because its a php file, i can pull any data i want from the vbdb and display it there, things i've thought about doing are having different sigs in different forums i already show different sigs to different users... i've done random images as well... Some great fun can be had with it
