    this reminds me or the color changing rolling ball thing ive been seeing a lot lately.
    its controlled by your phone and id love to make my own version because they are asking way too much for the commercially available one.
    perhaps a next step?

    either way this looks really cool :3

    Hmm, I believe you are referring to Sphero robotic ball - indeed it is pricey and order of magnitude more complex: it has bluetooth receiver (and remote app to control), servomechanisms (two independent wheels inside the ball), gyroscopic accelerometers and so on... plus it can glow :) Take a look on that review -> http://www.linuxgamenews.com/search/sphero
    I am missing a lot of skills (and free time) to construct such a device so I will think of your suggestion in a year or two :)
