get some of those 3-line blinky orange-pixel construction signs and array them on a landscape, somewhat hilly, so to as many are scattered in the line of sight as possible, such as laumeier or similar. And then:

a) haiku on each, or
b) social commentary across all 23, or
c) crazy pinball ascii art animated across them all

So, what does it take to get hold of these things?
