Games
Ravelvault
A self-contained physical aerial-acrobatics game. Hold the visible brass clasp between a complete gymnast's knees. Drag it toward the chest to shorten the body and reduce rotational inertia; drag outward to open and slow the turn. The same changing radius conserves angular momentum while gravity drives the swing. Lifting the finger releases both hands with the body's actual position and velocity. The airborne figure must cross three sequential seals, open from the tuck and bring both articulated arms within real reach of the receiving stave.
