A traditional gift for an ethnic minority in Vietnam - the hair comb.
This was an experiment with colour. The idea came from a piece of art I had seen about 6 years ago done on the old commodore 64. That machine was only 8 bit, and there were I think 16 colours available. People had really used the limitations of that machine to create some pretty amazing tech demos and artwork though. I believe that the interactions that result in limitations of a medium throw up some interesting new ideas.
