Peter Marigold's FORMcard is pocket-sized card of strong, meltable bioplastic that can be used to make, fix, and modify objects. The product is currently seeking funding on Kickstarter. The premise will be familiar to anyone that's ever used Sugru (I am a big fan), but the difference with this is that it is re-mouldable. I don't think the two products need to compete, but rather complement each other; different tools for different jobs!
