AR Code Generator
An AR “Bullseye” code generator on my laptop; it looks like a Bat signal but it contains data that can be read by a graphics card shader. Print it on a standard printer. A standard webcam and a GPU shader can pull out ID, position and directional information from these. Glued to the underside of an X-Wing miniature, software on a special table can track movement and rotation of up to 256 individual pieces per frame.
