∏+∏+∏+∏+∏+… ("Pi" series)

The ∏ (the Greek letter Pi) series works on the "piece of pie" principle. By taking a flat circle , cutting it along its radius and adding an extra "piece of pie" cut from another circle of the same size, the flat circle starts becoming 3 dimensional and continues folding as more pieces are added until you add so many pieces of pie that the circle becomes a sphere.
These sculptures are "developable surfaces." This technique of curving a flat sheet of material without stretching it is nowadays used by the most innovative architects in the world such as Gehry Associates (cf. Guggenheim Museum Bilbao, 1997).
