Friday Fun

This is kind of cool: three-legged – eh – things jumping up and down, holding hands (feet?), doing somersaults… I guess you just have to look for yourself: Acrobots

Update: I added the hands-on math&science tag. This is more than just fun or hypnotising to watch on a Friday afternoon…! You can add acrobots to the situation (by clicking on the big plus) and witness a sort of phase-transition: as it gets more crowded, the situation changes from individual bots bouncing around to one network moving, changing shape, breaking up and reconnecting…

It’s like… liquid water turning into ice? And the hands are the H-bridges between the molecules? OK, not really, the number of hands doesn’t make sense then, but well, something like that. Sorry, it’s Friday afternoon….
