RigidChips
RigidChips is a rigid body simulator video game developed by Takeya Yasuhiko. Objects and vehicles are constructed by combining parts with a scripting language. The program calculates air and water resistance realistically. Models can be made using any basic text editor or a fan-made 3D editor. Planes are controlled by changing the angles of flat pieces much like in a real airplane. Games can be made by assigning scripts to the constructed objects, including multiplayer network games. Using models with gun chips, multiplayer battles are possible. RigidChips was left without any official support from Takeya Yasuhiko with version  v1.5.B26 from August 2006. When Takeya became active again, he announced that RigidChips was "dead" and he is making a similar simulator called "Laputan Blueprints", which is in the proof of concept phase. Chip types. The building blocks, called chips for their square shape, are chip, frame, rudder, rudderf, trim, trimf, wheel, reaction less wheel (RLW), jet, arm, and cowl. All chips have an angle, a color, and an option.
