Tellart created a holiday card building upon opensource AR technologies and I created wooded blocks with the UID laser cutter to work as fiducials.

Early speed and power tests on the laser cutter

First Laser Cut Block Test

Will refine the software to capture the blocks as fiducials and then create a spelling game. The simple objective is to recognize three letters in a row by video: D O G. Will work on software back in Providence.
