ex·ap·ta·tion (noun)
The utilization of a structure or feature for a function other than that for which it was developed through natural selection.
I believe, we, as designers need to be constantly aware and curious of the use of objects (digital, physical, spatial) for functions beyond their initial intentions.
We constantly see physical object examples of this (newspapers as shims for tables, coat hangers as slim jims, etc.) yet what are the digital examples? Or spatial examples?
Perhaps the Occupy movement is showing one method of exaptation of parks & squares as spatial objects of protest.
