Using Foam as a sculpting medium

I was just curious how many of you out there are using EPS foam in producing sculptures. I use it depending how large an item. I see Tiki Diablo uses it too.. anyone else?

OK, I'll bite. What IS EPS foam? Where do you get it and what kind of results do you get? Got any pics?

Okay SilverLine thanks for asking. EPS is a short fancy name for expanded polystyrene or beaded white foam also known as styrofoam- which is trademark name by Dow? Kind of like how we all refer to a facial tissue as a Kleenek. :)
Search my old post and you'll see works I created out of foam!
