The small (1" diameter) Ozobot 'robot' gaming pieces bridge the physical and virtual online world with robots that respond to what they see beneath them on the tablet screen or tabletop or both. Basically, they move themselves! An interesting new innovation that could bring tabletop social gaming back to life. Devices and Apps not available until later this year, but I will be looking forward to trying this one.
The fun will come when lots of games and Apps appear.
