Through her large picture window, the eponymous Mrs. Squandertime watches the sea: boats, clouds, gulls, the tide going in and out, people on th...

The deployment of virtual characters in intermedia performance drives divergent agendas of this research group. From the perspective of performance studies, we examine the effect of computer-based characters as actors and believe explorations of mediated agency can open up new forms of engagement for live productions. From the visualisation point o...

Office Diva is a simulation of a monstrous ego; whining and writhing as she obsesses over her life. We see her as a fiery homunculus or dripping rain cloud barely holding together. We hear her stream-of-consciousness rant, and it becomes clear that this is a disturbed mind trapped by its own solipsistic and unreal processing of daily events.

Human Trials is simultaneously a public/private and embodied/disembodied performance. One user enters an immersive virtual environment and is led on an absurd quest. The challenges appear to be about control and the choices one makes in using power; but the games are rigged, the characters are duplicitous, the quest is a decoy, and the underlying t...
