Mike of Atomic Shrimp is always trying to invent, alter, modify or improve things. He sometimes runs out of ideas, so he made these dice to help inspire him. The six six-sided address different aspects of an invention: materials, motive power, scale, device, consumer and action. Mike writes:
Rolling the dice generates one of 46,656 different unique combinations - which the inventor can then use as inspiration for a brainstorming session.
Some of the combinations are nonsensical, but this itself can be provocative - and the ideas that flow from your imagination in this process don't necessarily have to fit all or any of the original criteria - it's just meant to spark the imagination.
They're like a Dungeons & Dragons random encounter generator, only with fewer orcs and more solder.
