ProtoSans04 by Roman Gornitsky is a free geometric techno display font assembled from uniform strokes and hard right angles. The construction is square and spare.
A technology brand or experimental music label could use its circuit-like geometry for a compact wordmark. It also fits game interfaces, electronic event posters, and product packaging with a deliberately engineered theme. The recurring rectangular bowls and cropped forms can echo grids, circuit diagrams, and block-based illustration.
