Laughing swing is an interaction between a person and a swing. It looks like a simple, regular swing. When you sit on it, it chuckles. As you swing, it laughs, and the higher you go, the harder it laughs. At the peak swinging it is laughing wildly.

Light Tracer invites the participant to write, draw and trace images in real physical space using a series of light sources. These light sources are subsequently tracked by a camera, and displayed over the participant’s own image onscreen.
