Rooms for Thought is a collaborative exhibition of Charlie Koolhaas and Madelon Vriesendorp, mother and daughter, which took place in Lucy Mackintosh Gallery, Lausanne, Switzerland.

Charlie created five different windows for a 'living room' which was inhabited by Madelon Vriesendorps cardboard sculptures of figures playing her 'mind game'. 

A collaborative installation - a series of rooms inhabited by objects - was the centerpiece of the exhibition.
