I've seen a few folks do a Bender costume over the years and some of them have been super elaborate. I don't have a woodshop or anything like that so I'm limited to making something fairly simple that I can do with my normal prop-making stuff and basic costuming equipment. I've already pretty much settled on doing the head out of either fiberglass or paper mache' but it's the body that I'm having trouble deciding on. Obviously something like one of those R2-D2 shaped BBQ pits would fit the bill AND already have a hatch on the front of it...but that'd be super heavy to wear around a convention and on top of that I've got to be able to transport whatever I make inside of a small hatchback car along with my other luggage. Ideas for the body?
