Moldable plastic for products?
trapper: Go lowtech and use shapelock or plasticene for prototyping. It's amazing how much you can do with plasticene, playdoh and other similar products. Some of the top design firms start out this way (ideo & frog from memory).Make some things and see how they "feel" with your product. At this stage you need to forget about styling and worry about how it acts.Then once you know what you want the product to feel like (even test it with potential customers), then make it look nice. There are plenty of people who can do that step for you, but the next step is usually a rapid prototype after designing in 3d for product testing.
