This shows the overview construction of the box and all the features of the small form factor.

48 IR LEDs aligned in rails above an LCD screen, create a Side DI setup, where blobs are created and picked up by the webcam below, which is then sent back to the computer to be converted into touch points.

(My computer is fairly old, as well as the low (24) fps of the webcam, so the Photo App runs a bit slow...Also it looks like my calibration was off a little)

    Nice one! Check out our mini we made out of cardboard. We didn't use IR but focused on shadows instead. I really like yours.
