Title: Brutalist Poster — Concrete Poetry Fest Creative prompt: Celebrate raw print culture with a poster that is also the ticket. Use heavy black rules, off-white paper, and flat red/yellow/blue inks with visible misregistration. It should feel loud, tactile, and unapologetically analog. Design description: A paper panel on black ground carries a giant grotesk headline, rotated red stripe, spec meta-band, live riso canvas poster, tabbed program, and a black sidebar with ticket-stamping widget; thick borders, dashed ticket edges, and CSS-shape ornaments keep it poster-true. Major visual techniques: - Canvas riso overprint with offset red/blue type layers and density control - Thick-rule grid, rotated stripe, marquee ticker, spinning star polygon - Pure CSS shapes (square, circle, triangle) instead of icons - Text-stroke outline headline treatment Interaction model: Tabs switch manifesto/lineup/workshops content; misregistration and ink-density sliders redraw the canvas live; color swatches plus stamp button claim tickets, decrementing the live seat counter and appending to the wall.
