design research::interactive projection mapping
Above is an interactive audio/visual installation where values are generated by live audio input in order to create evolving parameters on effects that a user can interact with over wireless midi control.
The above video demonstrates the installation and setup process for this piece, as well as a 10 minute live performance to Alva Noto’s “Haliod Xerrox” (The choice of this particular audio was due to inspiration from a projection mapping installation created by Alva Noto himslef you can view here: derivative.ca/events/2012/Unidisplay/).
The content featured in this piece was sourced and decided on based on a live video mixing technique dubbed the Eclectic Method approach (vdmx.vidvox.net/tutorials/how-to-do-an-eclectic-method-remix-overview) where you set yourself a theme, source video material to mix with, and jam with the clips on a MIDI or OSC controller as if playing a drum machine or instrument. In this case, I set myself the task of hunting down various water and under sea life clips from creative commons and public domain online archives.
Using VidVox VDMX5, I constructed and developed through experimentation an interface preset with all my desired clips and effects. Using a base level sound patch for the mac called SoundFlower, I was able to route audio from iTunes into VDMX to be analysed and run through filters to generate parameters for the effects built on each layer.
Once the VDMX interface was running smoothly, and the effects and clip selection tools were all up and running, I programmed my own MIDI interface on my iPad using Liine’s Lemur app. I based my interface on a mixture of drum machines and slider controllers I have seen used in live production, designing it to be as simple and easy to control as possible for live performance. The pads on the right of the interface all representing clips in the VDMX media bins, on and off switches for effects above, and audio input parameter control over the effects on the left.
Once up and running, it was time to project it onto something!
While digging in the recycling bin behind Dick Smith, I uncovered a heap of fresh cardboard boxes which I used to build the structure to project onto, and built my own “ghetto” rig to mount the projector to the ceiling.
The live video output from VDMX was sent through to MadMapper via Syphon for mapping onto the boxes. I then mapped each face of the structure with three different layers of video.
Voila! The installation is all running
This clip displays a sneak preview of an interactive installation I contributed to Museum of New Zealand, Te Papa’s first ever maker’s fair Makertorium.

In this video James Crane and I perform an audiovisual investigation into live feedback loops. Koi (James Crane) is a culmination of experimental, industrial, and grunge electronica creating vast soundscapes that push your knowledge of sound into new dimensions. The live feedback loop I designed for this performance is a visual response to the dimensions Koi has pushed me.
