very interesting to me,
technically 2 is all one needs to create a sort of 'mesh' network and make multi puck implementations.
we are working with an artist which wants to prototype a toy that displays data structures
she is a double major [industrial design and computer science].
we are trying to make the toy 'smarter' by making each 'data' self aware.
we really wanted to start exploring this in the Espruino environment but we need to use multiple pucks which can send data between each other.
