Maximilian Rödel’s “Fortunator” is green; it’s blue; it’s also yellow, or at least a close variation to all of these colors. And it’s almost square, but the interlocked colored areas make it hard to clarify. So unclarified it sucks, draws, and dizzyingly swindles the viewer into Rödel’s abstract pictorial cosmos, leaving him enough room to give the audience a sensory experience through the abstract shapes.
