With Theo Botschuijver
A custom laser scanning system was developed that could project the laser beam as shaped planes and cones of light in a full 360-degree space around the projector. Scanning and rotation of the laser mirrors was controlled by a specially made analog synthesizer. Materials such as smoke, water vapour and material particles were used to visualise the moving laser beam and so create immaterial kinetic architectures of light. This technique was used for two Genesis concert tours. The presentation at de Appel explored the possibilities of an interactive electronic connection between a live cello performance and the consequent articulation of laser-generated light forms.
