I guess you really can find beauty from one of the worst blights on our cities: billboards.
These stunning photographs are by Branislav Kropilak. He also has some beautiful images of parking garages on his website.
If only we could see the billboards from this vantage point on a regular basis. Looking up from below really highlights the amount of light pollution many of these billboards put off as well. (And they don’t get turned off – they are typically on all night.)
