Mass decides behaviour
The heavy card (mass 3.2) resists the pull; the light dot-accent (mass 0.3) gets flung around wildly. Chips and rings each have their own gravity personality.
A tiny system of shapes, chips and cards. Your cursor is the sun — objects orbit it by mass, some eager, some indifferent. Move it and watch them tumble.
Within 190px of the pointer an inverse-square pull attracts each body by 1/mass; a mild repulse stops them stacking on the cursor, and a spring pulls every body back to its anchor.
The heavy card (mass 3.2) resists the pull; the light dot-accent (mass 0.3) gets flung around wildly. Chips and rings each have their own gravity personality.
When the cursor leaves, bodies don't snap — they wobble back to their anchors with per-body phases and amplitudes, so the scene stays alive on its own.
