Watch an Octopus Count in Binary

Nice! An animated video of an octopus learning how to count in binary. Originally created for an introductory computer science class at Rutgers University. Watch how each tentacle represents one bit. Eight tentacles = eight powers of 2! A great way to teach students how to learn the basics of binary arithmetic.
