How to make a Star Trek on/off switch

Found via BoingBoing:

LCARS panel

This great HOWTO illustrates the process of homebrewing your own Star

Trek: The Next Generation On/Off switch. I'm thinking it would be a

great controller for a garbage disposal -- tell your kids that it's a

"transporter" and encourage them to "beam down" their left-over

vegetables (but caution them strongly against "transporting" their

hamsters and siblings, of course).

Technically speaking, this is an LCARS panel, but why quibble over technobabble. My wife would totally veto this, but a geek can dream, right?
