Falling Sands

A collaborative pixel sandbox on the Usernode blockchain. Draw with physics-simulated elements and watch them interact in real time.

• Pick an element from the toolbar (tap the swatch to see all elements)
• Draw on the canvas — strokes appear locally as a preview
• Send your strokes (tap the check mark) to commit them on-chain as a transaction
• Everyone runs the same deterministic simulation locally

Each stroke is stored as a transaction memo on the Usernode blockchain. Your device runs the physics engine (WASM) locally.

Tap anywhere outside this panel to close.

This wipes everyone's drawings back to the seeded default and is recorded on-chain.
