How about one of these at the Abq MMF? Working with the city of Abq to put one in a park? With sound? (need to be in a tent during the day...)

How long has it been since you were on a seesaw? Perhaps the plank-and-fulcrum toy of your youth no longer holds any interest. But add some blinky lights and a fancy enclosure (http://www.eness.com/?r=Project&p=32&c=) and folks are lined up to get back in the saddle.

The video after the break gives just a glimpse of what's inside of this thing. There are 33 sets of LED strips wrapping the plank from on end to the other. They're covered in a translucent shell (we'd guess it's acrylic that has been heated and bent). Judging from the children walking in the middle, it's engineered well enough to hold up to some abuse. The seesaw can sense a change in orientation and sends light cascading from one end to the other as if aided by gravity.

We really like the clean lines of the installation; the spartan center mount, the use of half a tire as a ground bumper, and fact that the very end of the plank also lights up. If we happened upon this (it's in Melbourne, Australia so not likely) we'd wait a while for our turn!
