Whenever I think of futuristic worlds and holograms, I always think of simulated nature--whether that be animals or plants. For the "Holograms of the Future" Challenge I decided on fish...because fish seemed sensibly fluid (and elegant) mixed with some harder edges meant to vaguely represent loose digital pixel sets and a center column to give the fish a central anchor.
