Adds that are ment to be seen from the sky or satalite imagery.

Maxim magazine celebrated its 100th issue by building a 75-by-110-foot billboard featuring its cover image of Eva Longoria, billed as “TV’s Sexiest Earthling.” The billboard doesn’t tower over a highway, however. It’s flat on the ground so that it can be seen from a satellite.

I seen it is awesome, have you seen 3D advertising? i don't remember the page where I seen it, but i will find it again.

Hey, how about "crop circle" advertizing? Say someone cuts just certain areas of a field and leaves a design that advertises a product. An old type that could stand a comeback would be barn and building sides painted as signs.

Yeah I seen it, but the cost for that!, and the fact that people wouldnt know where to find those ads online, or what type of people to focus?
