Fibres Out of Line is an interactive art installation and performance for the 2021 Rhythm Perception and Production Workshop (RPPW). Visitors can watch the performance, and subsequently interact with the installation, all remotely via Zoom.


Passcode: XXXX


Participants are recommended to enable stereo audio in Zoom.


The Fibres Out of Line installation consists of 10 autonomous musical agents, setup as is shown in Figure 1.
Figure 1: The setup for the Fibres Out of Line installation and performance.
There are 8 Dr. Squiggles musical robots that play acoustic sound, and 2 software agents that play sound through speakers. These break down as follows: More general information about how these agents are constructed, and how they behave can be found in the following videos and links, and elsewhere on the internet.

We wrote a Make Magazine tutorial so you can build your own Dr. Squiggles: Learn more about the Dr. Squiggles Project:

Windchime Mode

The installation has two interactive modes. By default, Windchime Mode is active. A functional diagram of this mode is in Figure 3.

Windchime Mode behaves as follows:

Rhythmic Mode

Rhythmic Mode is activated when the performer or visitor waves their hand around rapidly in front of their camera for a few seconds. It is deactivated when there is no movement at all in the camera for a few seconds. A functional diagram of Rhythmic Mode is shown in Figure 4.

Rhythmic Mode behaves as follows: More information about how the tapping robots track the beat and generate rhythms is published in the Journal of New Music Research: Read the Article Online


Figure 5: Streaming Setup
The entire setup is streamed over Zoom via several cameras and microphones as illustrated in Figure 5. This allows the performer and participants to interact with the installation through Zoom video and, at the same time, to view and hear the installation. A number of independent devices with cameras are also set up, which will join the Zoom session as participants, and participants can view different scenes (close and wide shots) of the installation. The performance will be recorded at several locations: Zoom, local PC (OBS), Tablet camera (SD card), and Garmin VIRB 360 (SD card).


On 22 June at 21:40 CET on Zoom, the performer Jen Gerry will improvize a ˜10 minute dance performance with the robots. Jen is in California, while the robots are in Oslo. Both Jen and the Robots will join a Zoom session, so they can see, hear, and respond to one-another as described above. This is depicted in Figure 6.

Immediately following the performance, and continuing for the remainder of RPPW, participants will have the opportunity to join a Zoom room and interact with the robots. This is deepicted in Figure 7.

The system works best with one participant at a time, so it might be a little chaotic immediately after the performance as many people may attempt to interact at once. Participants may have a better experience if they come back later at a random time. RPPW atendees will be emailed the Zoom link, and anyone can obtain it by emailing Email

Enable Stereo Audio

The performance and installation will sound better if you enable stereo audio in Zoom. If you don't do this, you may only hear mono sound. There is an option for this in the audio settings, as shown in Figure 8.

The installation and performance are the result of a collaboration between the RITMO Center for Interdisciplinary Studies in Rhythm, Time, and Motion at University of Oslo: RITMO and the Driven Arts Collective: DAC The performance was hosted by the Shawl-Anderson Dance Center: SADC and was shown at RPPW 2021: RPPW No contact mics were harmed in the making of this piece.
