Multipoint Slideshow Display

Inspired by the Club Fair Attention Monopoly project used to make other clubs' booths stand out, this uses WebSockets to allow multiple users to point with a "laser" with their phones on a slideshow display.

Note: While I do intend for this to be used for my own club, this was entirely made by myself (not club members).

Demo instructions: Use your phone as a pointer and your computer/tablet as a display. Try touching and holding on your pointer's screen and see how it moves on the display. There is only one "group", so you might see others' pointers!
