Part of the Art of Collaboration series, created in collaboration with Eric P. Krantz.
While Krantz was an invited resident fellow at the Academy of Media Arts (KHM), Cologne, he worked with Pepper on a series of colour holograms which explored graphic shadows and colour-mixing.


Two papers were written in connection with this work: one by Pepper, on the creative interrogation of the piece and its production, and one by Krantz, on the scientific and technical aspects of the process.


Both were presented at SPIE conferences and published as part of the conference proceedings.
