This piece allows people to place duct tape on the wall, which is then scanned and turned into a playable platform game that is projected onto the screen. It’s one of those ideas that, once thought of, is relatively easy to implement, if only one had the idea first. This piece is relatively old (2006), but in case anyone was not yet aware of it, here it is.
I think it is meaningful because it is a creative combination of the physical world and the game world. I could also see something like this turning into a creative tool for level design.
