Ooh, creative homework for something other than arts class. That's rare. Can you tell us more about your assignment?
I was inspired by you. Blender internal renderer.
Well thank you for your interest in my work.
we have to create an advert containing presentational devices (slogans, personal pronouns ect) I just decided it would be fun to make a model of my idea.
Its a battery cell that is powered by the heat of the device or the heat of the body.
