All of these projects fed into a collective culture in the group - with Justen Hyde, then a research student studying the reconstruction of human facial images, getting sucked into the work, making minor contributions to all of the projects, though officially working on none of them. The projects most often wheeled out to demonstrations were quickly established as PenPets (O'Mahoney) and d-Touch (Costanza) both of which had a strong commonality - they appeared to work by magic. The computer could be hidden from view, and the user could then simply interact with the augmentation directly. In the case of d-Touch, by moving marked blocks in front of a webcam to sample, edit and produce music with very low-cost paraphernalia - just a cheap microphone, printed fiducials and a standard PC. PenPets required more of a hardware overhead - a data projector pointed at a table. Onto this agents resembling mice were projected. These would run around the table, bouncing off hands, pen marks and objects.
