Performance comprises a variety of aspects - the computer, the user and the interface. The computer programming has been optimized to display only what is necessary for the user at the time. The user's performance depends on efficacy of the visuals in collaboration with the head-tracking device and navigational wand. The visuals in Dream Grrrls will invite the user to explore his ability to control the environment and realize what constraints he has. Dream Grrrls becomes a medium for the user to create his own performance.
