Description
"The OpenStructures (OS) project initiates a construction system where everyone designs for everyone.
It is an ongoing experiment that wants to find out what happens if people design objects according to a shared modular grid, a common open standard that stimulates the exchange of parts, components, experiences and ideas and aspires to build things together." (http://openstructures.net/pages/2)
