I like doing fun things like that and it can work both ways; I once was having trouble with an office vending machine, was eating too much junk so turned it into a troll with snotty nose, ugly name, dirty fingernails, bad breath, etc. I actually felt a little afraid if I was in the work kitchen by myself, LOL.

As long as you know you have an excellent imagination and that it is you creating the character (think Jim Henson and the Muppets :-) it is a great use of creativity and imagination, I think.
