A real-life implementation of the evergreen arcade game Tetris was obtained by optically trapping 42 glass microspheres (1 μm or 0.001 mm diameter) in a 25 μm x 20 μm sized area under a microscope. Their positions are then steered with a computer.

    Are you using more than one laser here, or are the spheres manipulated through "time-sharing" of a single laser? In any case, very impressive!

    These glass beads are pretty light-weight: 1 pg (picogram or 10^(-12) gram...

    However, you could in principle do the same trick with bacteria, to get somewhat closer to live pac-man! :-)

    Whoever was playing isn't very good at tetris. xD

    I'm just kidding.

    Cool video.

    Could use some background music though.

    @UALGProduction Hehe, Tetris microscopes are not out yet -- it was a self-built microscope we used.
