Pocket AI
Just about everyone has played the game of '20 Questions', but have you played it with a small plastic sphere? Originally a DOS neural-net program passed between friends via floppy disk, the AI has been training online since 1995. The neural-net has since been trimmed to its most popular objects and most useful connections and programmed into a small 8-bit chip. You can now buy the chip inside a plastic ball that is uncannily good at guessing your objects.
