This very entertaining take on the classic most useless machine gag is not quite so patient as its ancestors. Oh sure, it does what they all do: When you turn it on, it turns itself off. And it’ll do that over and over again. But, much like my college roommate, the machine has its limits, and it’s probably wise not to push it too far. [via Hack a Day]

    That is awesome!

  3. That was beautiful! It just kept getting better and better.

  4. New twist on a useless machine


  6. Definitely awesome, and gave me a good laugh. but what’s with all of the “face” changes on it? Slide-out panel to make it look angrier as time went on?

    Haha, that’s cool, but i was expecting it to explode, or let out a freaky scream or a yell or something. Endless possibilities as to what people will thing up.

    hahahaha, i didnt even read the description so i was like “sigh not one of these again” but then it started flipping out. i want one. maybe they could have an lcd panel instead that changes facial expressions ;x

    I was expecting an airsoft gun or some sort of launcher, maybe something that tried to smack your hand. Maybe add a motion sensor and have it anticipate the switch flipping. I like it though.

    I could almost feel the anger….almost…and as for the uselessness, well no argument here.

  11. Scott House says:

    It needs a POV display (Stop sign, Angry face, etc…) for when it’s spinning…

    I’m almost laughing too hard to comment on this! I love it!

  13. I think Linda Blaire built this one…

    I especially like how it retracted the switch after throwing its tantrum!
