Contraption Maker by Spotkin
“The team that created the original Incredible Machine® is bringing all of the Rube Goldberg craziness to the modern age.
Solve puzzles involving ridiculous chain reactions full of hamster motors, trampolines, alligators, cats, and so much more. Then go to the powerful Maker Lab, where you can create your own contraptions. Everything you loved about the original game is back and improved with a new physics engine, high definition art, and new parts and programmability.
Our community features will allow you to share your creations with the world. Cooperative play, subassemblies, mods and more are coming soon. Keep a eye out for the Early Access (Alpha) release coming to PC & Mac this summer!”

Oh wow! I loved the Incredible machine when I was younger.
