Even more useless once the batteries run out.

My favorite useless invention was this box that kept its lid half open, but if anyone got close enough to try and look inside it slammed shut like an angry clam until they went away.

This is what The Box should have been, Cameron Diaz flips the switch and its two hours of this followed by credits.

WHy can't someone make an anti-rape device out of this?

THAT IS AWESOME!!!!!!

This is a make me happy machine.

It doesn't WANT to work.

I WANT THAT!

I have no mouth and I must flip toggle.

The operation and spirit [of "The Ultimate Machine.''] were described by Arthur C. Clarke in his book "Voice Across the Sea: Telstar and the Laying of the Trans-Atlantic Cable":

"Nothing could be simpler. It is merely a small wooden casket, the size and shape of a cigar box, with a single switch on one face. When you throw the switch, there is an angry, purposeful buzzing. The lid slowly rises, and from beneath it emerges a hand. The hand reaches down, turns the switch off and retreats into the box. With the finality of a closing coffin, the lid snaps shut, the buzzing ceases and peace reigns once more. The psychological effect, if you do not know what to expect, is devastating. There is something unspeakably sinister about a machine that does nothing -- absolutely nothing -- except switch itself off. "

Someone should make a version of this powered by the clapper.

Now you need to build a machine that switches the first machine on and we've invented perpetual motion!

They're wrong, this machine is highly useful. Just not to you.

:D

Oh, I wish it wouldn't keep turning itself off. I want to see what it does!

NO

NO

FUCK OFF
