Rigid Chips is almost like a virtual set of legos, except you have parts like V8 engines, rocket thrusters, laser ring gyroscopes, and guns. You can also add scripting to your models so you can make things like segways and autonomous vehicles. If your really ambitious you can also script “scenarios” or basically games you can play in Rigid Chips. You can also make your own levels. Rigid Chips even has a multi-player mode so you can do battle with tanks, airplanes, hovercrafts, cupcakes, or what ever else you can think of. There are many rigid chips models and resources available online.
