This demo for bubblePLY, a service that allows you to add “layers (PLYs) of bubbles that are synchronized with a video on a player”, is great. The video is blurred when there is a new instruction, in text form, which made me pay attention to what I was supposed to be learning. The background music reminded me of something I would hear in a club if it was “80′s” night, but it doesn’t take away from the presentation.
