The sculptures shown on the left were conceived and created by Wout Zweers, Valerie Zwart and Onno Bokhove as part of their work on a paper entitled Making waves: visualizing fluid flows. They were donated to the Newton Institute by the Stichting Free Flow Foundation. To create the sculptures, a film was made of splashes in a wave channel at the University of Twente, and the individual stills were examined. Outlines from a chosen set of stills were then traced by hand before being modelled into three-dimensional pieces. The sculptures can be viewed in the Institute Library.
