[NetBehaviour] Discotrope is an audiovisual performance by Amy Alexander and Annina Rüst

[info]

Discotrope is an audiovisual performance by Amy Alexander and Annina 
Rüst, with sound design by Cristyn Magnus. Performances invoke both 
alternative energy and the curious history of dance in cinema – from 
backlots to backyards.

Discotrope events can range from seated concerts and gallery 
performances to public space dance parties. We’ll project moving images 
of dancers – both party attendees and recorded clips – onto the 
Discotrope ball. The video dancers power the ball, literally and 
figuratively: the ball uses solar cells as disco ball mirrors. So the 
projected dance videos not only reflect off the ball, they also 
“solar”-power the motor that makes it rotate – which creates 
zoetrope-like projections on the surrounding walls, floors, surfaces, 
and people. We’ll perform the ball live, adding color and light effects 
to the video projections that vary the amount of light to the solar 
cells. That changes the speed of the ball’s motor, which allows us to 
“choreograph” the movement of the projected visuals as they move around 
the space.
