About this category
Randomizers, quick decisions and recreational instruments
This category brings together tools for playful moments and quick decisions: flipping a coin when two options are equal, rolling dice for tabletop RPG or board games, keeping tempo while practicing an instrument, or simply exploring a melody on the virtual piano.
The visual highlight is intentional: each tool has its own carefully crafted animation — a coin spinning in the air, a metronome pendulum with real physics, a die rolling in 3D. All processing happens locally in the browser.
