Planisim A vey rich simulation of the physics of a 2D world.

Quad A 2D animation of quadruped gaits to investigate their relative stabilities

Sim3d a 3D simulation of hexpod or quadruped walking. You can design your own leg controllers.

Flowchart a simulation system with a graphical interface

Tether a simulation of a rotating-tether satellite

Asteroid Animates detonating a bomb on an asteroid to prevent it hitting Earth. Is the asteroid destroyed or deflected. The simulation was created using Planisim

Water how to animate ripples in a photo of water

Tripod an animation of the gait of a Martian war machine
