Title: Bauhaus Motion — Circle Square Triangle Creative prompt: Kandinsky's Dessau trio set loose as a living physics toy with gravity, fling-to-throw dragging, and shape-counted collisions. Red circles roll fast, yellow squares thud heavy, blue triangles spin sharp while trails and grid flashes track every impact. Design description: Strict Bauhaus ledger with thick ink rules, paper background, and a gridded white playground beside a manifesto column of speed/gravity/trail sliders and spawn/clear actions over a red-yellow-blue primary strip. Visual techniques: - Canvas rigid-ish bodies with shape-specific draw and spin - Wall bounce physics, drag-vector fling, and trail ribbons - Collision screen flashes in the striker's primary color - Faint 48px construction grid with fade-persistence trails - Shape-filter spawn modes from the header glyph buttons Interaction model: Header buttons filter spawned shapes, sliders drive speed/gravity/trails, clicks spawn bodies, drags fling them along the vector, and spawn/clear buttons manage the population.
