Double Pendulum
Open with main menu g, then Games 2.
A coupled double-pendulum chaos demo. A lighter tip mass and longer second arm make the path diverge more easily; the tip trail is drawn as a fading color ribbon.

Notes
- Uses the classic double-pendulum angular accelerations with semi-implicit integration and light damping to avoid energy blow-ups on bad frames.
- Multiple substeps per frame; the tip trail is a ring buffer of about 72 points.
- The near bob is larger and the tip bob smaller to match the mass ratio; the top label always shows
CHAOS.
