We finally have it, people. A computer so small it is comparative in size to a grain of rice. But do not let the size of the M^3 (real name: Michigan Micro Mote) fool you. It is completely capable of taking pictures and reading temps, among other things. It was created by the folks over at The University of Michigan with help from professor David Blaauw and is intended to help people keep track of valuable items.
So all those movies where superheroes slip “trackers” onto things to follow them, it’s kinda like that, but in real life.
