I think I need an aspirin. Thanks to one of our stringers in Florida, we were linked to this fascinating video of an animated building---the former headquarters of Bayer in Leverkusen, Germany. This is called a "media facade." It is composed of 5.6 million LEDs over a 17,500 square meter surface. We can't imagine having an apartment overlooking this enormous vision! Imagine a whole neighborhood of such facades.
The gargantuan advertising form creates an intense kind of visual pollution that curtails any ability to say "No!" Also, seeing a piece of architecture used in this way makes us weepy.
For a look at how the LED plates were constructed, here's the link.
