plaYcard
plaYcard is sophisticated toy yet cheap to build, simple to install and fun to play with. You make the contents of the crosswalk and it will make all that pass aware of your design. Its surface geometry transforms according to site parameters of street width, length, and underpass slope. Subdivided by a diagrid, the surface pattern resembles a collection of placards, although its message is one of awareness rather than alertness. Its reflection is in a constant state of change, just make sure you color within the lines!
