This 2D companion drops the rotatable 3D sheet in favor of a flat, always-visible grid that is easier to pop quickly: click or drag across any number of bubbles, and each pop plays a synthesized click whose pitch scales with the bubble's size — a small nod to how a smaller trapped-air cavity rings at a higher frequency than a larger one, the same principle behind using an impulse pop to probe a room's acoustics. Tune the grid dimensions and bubble size with the sliders, watch the pop counter and percentage climb, and hit "Pop all" for a satisfying cascade across the whole sheet.
