Individual letters or parts of letters are printed on each face of a cube, so cubes can be placed in rows to form words, or cubes with letter fragments can be stacked to create letters at a large scale. They’re then placed on blank wayfinding infrastructure that has a small lip to hold them up. The resulting system is similar to a beautifully considered mega game of Scrabble, and can easily be adapted to meet the needs of the community it serves. – Fast Company
