Glohst was a 2010 public arts project by Milton Keynes artist Meechy. Permission was gained to stencil clues on public places around Milton Keynes that could only be seen using a UV torch. An added dimension was that some clues required chromadepth 3D glasses to separate colours (reds nearer, blues in the distance). These clues would lead to web pages which gave clues to the location of the next puzzle.
My contribution was logo design, font design, location scouting and project management.
