The initial sight of a triangle accompanied by some piano music reminded me of the BBC snooker show “Pot Black” from the 1970s. This one, though, is somewhat more adaptable as by using a series of colours and some nifty manipulation we watch this geometrical shape prove it’s flexibility in what looks quite like a ballet. There’s a synchronicity to the artistry here as the images constantly change to present objects that ought not to seem possible for a fixed, three-sided, solid to achieve. The score helps it along engagingly and it’s simplicity and clarity of definition works quite well for five minutes.
