A similar thing from many years back: the junkyard jumbotron let you assemble a random collection of displays to display their portions of a much larger image
The Media Lab makes so much random fun stuff. I feel like it would be fun to remake this with modern web tech. (doing the alignment photo over email does sounds like fun too hehe)
