Rapid visualization of key solution concepts — 8 sketches per core feature area, exploring different UI/UX approaches before converging on final designs.


What is Crazy 8s?

Crazy 8s is a rapid sketching exercise where designers create 8 different variations of a solution in 8 minutes (1 minute per sketch). The goal is to push beyond the first obvious idea and explore diverse approaches.

Adapted for this case study: Each core feature area has 8 conceptual sketches showing different UI/UX approaches, represented as wireframe descriptions and ASCII visualizations.
