The Spark Festival of Electronic Music and Arts had a lot of cool pieces but one of my favorites was â€śButterflyâ€? by Niknaz Tavakolian. It was a big circuit connected to a bunch of flaps along the wall. I wasnâ€™t sure what it was until I started walking past the piece and it started moving! I think its really creative how they connected the wings to a motion sensor so the wings flap as you walk by. It creates somewhat of a wave action as you walk along the piece of work. It reminds me of a butterfly by the use of a central body circuit and then the moveable wings that branch out from the center.
