Via BoingBoing, some companies are painting the tops of their buildings so they can be viewed from space.
If this elicits a "Huh?" response, keep in mind that tools like Google Earth give everyone on the planet a free satellite view of their neighborhood. Target is doing this, but others are sure to follow. And it makes perfect sense; if someone is trying to find a Target store, a giant Target logo visible from the space view works.
It's a great example of how technology is changing the way we do things (in this case, advertising). And if you have not tried Google Earth, you should, especially if you are involved with economic development. Be assured that most companies considering relocation are already using Google Earth as part of their site assessment prior to a visit.
