On April 22nd the Swiss Post published a set of two stamps dedicated to Swiss contemporary architecture. The sister stamps reflect projects of Gion A. Caminada and Müller Sigrist Architekten AG. Both design firms use Vectorworks. The Müller Sigrist project, a concert hall called Pentorama, is the subject of a short film produced by the Swiss cultural webpage art-tv.ch. It's worth a peek.
