Afterglow is a presentation system that allows you to draw and point on a projector screen using a laser pointer and a PC. First announced way back in 2007, the system is now available online for $1980.
The product can be used a a pointer on the screen to control the mouse or as a virtual “pen” to draw lines and arrows on presentations. Larger implementations would allow for digital graffiti to appear on the sides of buildings.
