DNA

This work was commissioned by John Bonnet as part of his outdoor Datascapes virtual reality project that was shown at Brock University in May of 2014. I was given a short sequence of numbers he had extracted from DNA sequences and asked to make a video that used these numbers in an essential way. The problem was how to create visual interest from the very small amount of data I was given. The remedy was to use the relationships between consecutive strings of the numerical sequence to produce the video you see here.

Ice Flow

I'm interested in systems that grow and decay according to very simple local rules. What is remarkable here are the large scale complex structures that arise as this system evolves.

Red and Yellow

Each of the frames in this video is a visual representation of a discrete dynamical system of the form xn+1 = f ( xn ). The function f was chosen after a great deal of experimentation and depends on many parameters. I slowly vary these parameters to create the continuosly evolving animation you can see here.

Portrait

This video combines photographic data with the output of a discrete dynamical system to create a portrait of the artist Bruce Thompson.

I was asked by Professor Sid Segalowitz and James Desjardins in the Neuropsychology department at Brock University to create a visualization of the data they were collecting from sensors attached to the scalp. They stipulated that the animation had to run in real time as the data was being acquired. With so much data being output so fast, I had to restrict myself to just drawing rectangles in order to keep up with the flow. I used the pairwise correlations of the data streams to determine the position and colour of each rectangle. Absolutely everything you see in the image, such as colour, size and movement, comes from the output of a human brain.

This video is an animation of the data obtained from sensors attached to the scalp supplied by Professor Sid Segalowitz and James Desjardins in the Neuropsychology department at Brock University. The Fast Fourier Transform is applied to the data and the output is massaged by me and then plotted to obtain the animation shown here.
