HandMask

Hold up both hands — your thumbs and index fingers become the corners of a box, and whatever it frames gets distorted.

Click effects to stack up to eight — they compose, and the number shows stack order. Frame tracks your fingertips live; Draw pinches and traces an outline that stays. Pin leaves the current shape behind with its effects. Dragging with the mouse stands in for hands. 1–9 toggle · R random · X clear stack · F mode · P pin · U undo · C clear · S save
