What does light do to our brains, how do we register movement, how does sound feel, and do we actually see what we think we see? In his art works Philip Vermeulen explores our perception through movement, light, vibration and sound. The exhibition Chasing the Dot in Rijksmuseum Twenthe shows six room-filling installations. Hiska Bakker interviews Josien Beltman and Annelien Dam (both from Rijksmuseum Twenthe) about the spectacular realization of this exhibition. In cooperation with Student Union.
