## About

Impossible Machines is a prototype exploring declarative programming for the physical world. Users specify what they want the system to do, and a mechanism appears based on the rules and environment described. It features interactive challenges and a freeform bench to experiment with physical components.

## Who it's for

Makers, designers, and developers interested in experimental programming and physical mechanisms.

## Use cases

- Exploring declarative programming concepts for physical systems
- Solving interactive physical mechanism challenges
- Experimenting with custom mechanism designs on a freeform bench

## Features

- Declarative system input to generate mechanisms
- Interactive challenges including detours, brakes, and guided turns
- Freeform bench for open-ended experimentation
- Landscape mode optimized for mechanism exploration
- Components including cranks, weights, blocks, brakes, guides, obstacles, sinks, bells, and doors
