While strolling the isles of my local Best Buy store, I noticed a huge
50 inch computer monitor positioned well above the shoppers heads. It
could be seen from anywhere in the store.

I walked over to play with the computer and told the floor salesman
I'd like to play with it for a while.

I set it to automatically play the HD videos from YouTube's "Gliding
TV" channel with spectacular videos of soaring over the French Alps.
Then I stood back to watch reactions. About 2% of the crown of
shoppers walked up and said something like "way cool". The other 98%
probably didn't have the "Gliding Gene" and didn't react at all.

The store manager walked over and said he thought it was a great way
to show off the monitor so I expect the video will be playing for a
while.
