Presentation

Flowing light & particles

The curved surface illustrates gravity. Use 3D, 2D or Split to explore your system.

Dragging empty space

While you aim, the dashed line predicts the path: green bound, orange escaping, red collision. Alt/Ctrl-drag always rotates the view.

A violet background galaxy hides in the sky. Orbit the camera until it slips behind the hole and watch its two images stretch into an Einstein ring.
