To promote the movie adaptation of 'Where The Wild Things Are' a Yowl Booth toured the country. (Yowl is like a howl and a yell, makes more sense if you see the film...) Inside this booth kids or adults would go inside and 'yowl' as loud as they could at a large TV screen which showed a tranquil woodland scene similar to that in the movie. The louder participants yelled the more destruction would impact the forest, at the end the people in the booth was given a marks out of ten and told how loud they yowled.
You can see an example of this in the link below or at the top, tho I find screaming children extremely annoying so i wouldn't recommend watching for too long.

Screaming kids locked in a booth sounds sinister but at
Nerv we had to make the visuals for the on screen animation. Below is some screen shots from the final animation I made, the images don't really do it justice as hundreds of leaves and branches whirled around in an intense way but just being involved with a Spike Jonze film to this tiny degree was awesome! Though animating it did nearly kill me, still im better now....
