Here is a magnificent use of billboard space created by architect Didier Faustino. He has titled the work/installation/swing-set Double Happiness for pretty obvious reasons. Clever ideas like this usually don’t come from passivity towards the city, but an engaged, analytical, and curious attitude. I found this summary of the conceptual framework behind the project:

“Double Happiness responds to the society of materialism where individual desires seem to be prevailing over all. This nomad piece of urban furniture allows the reactivation of different public spaces and enables inhabitants to reappropriate fragments of their city. They will both escape and dominate public space through a game of equilibrium and desequilibrium. By playing this “risky” game, and testing their own limits, two persons can experience together a new perception of space and recover an awareness of the physical world.”
