Tony Robbin had started out as a painter. He created complex works filled with interwoven patterns and ambiguous figures to give the illusion of seeing more than one object in the same place at the same time.
“I was interested in ways of experiencing and depicting space—complex spaces, multiple spaces, paradoxical spaces,” Robbin recalls. His fascination with finding ways to look beyond our three-dimensional universe inevitably led him into the domain of four-dimensional geometry.
