Gyroscope in gimbals
This osp3d applet animates motion of a gyroscope in massless gimbals. Operator can set initial conditions for its motion and an offset of the massive cylinder from the fixed point of the gimbals.
Double Pendulum
Display animating motion of a double pendulum. Its two legs are made of a homogenous massive material.
Hypercube projections
This display shows projection of a 4-cube into a flat 3-dimensional space. Operator can rotate the 4-cube in all main six planes and observe consequent changes in its projection.
