North and East
Time-lapse photos from the Rubloff office at 750 N Lake Shore Drive. Photos taken using my iPhone, carefully positioned in the corners of the north and east windows next to my cubicle. Angle effect is achieved using a Quartz Composer composition, which dynamically reads the photo albums created using iPhoto.



A Portrait of James D. Watson in his own Words
According to Wikipedia, "a portrait is a painting, photograph, sculpture, or other artistic representation of a person". Instead of simply using color pigments, we use unique portions of Dr. James Watson's DNA sequence to portrait himself. Dr. Watson was the discoverer of the structure of the DNA and helped to establish the Human Genome Project. DNA, as a primary genetic material, defines the molecular signature of oneself. Dr. Watson's DNA was fully sequenced and made public in 2007 by The Baylor College of Medicine Genome Sequencing Center, 454 Life Sciences Technology, and The Rothberg Institute. We used the SNPs, which define the small differences of DNA from person to person, to uniquely represent Dr. Watson. In order to do this, we took the variant allele base pairs from Dr. Watson's genome (Cold Spring Harbor Laboratory distribution, 6/6/2007) which had a sequence observation count greater than 12, and generated a portrait capturing his phenotype.

This piece won first place in the Visual Reflections on Science contest at the Intelligent Systems for Molecular Biology (ISMB) conference in Toronto (July, 2008). Awards were determined by a vote of conference attendees. I made it using Python and the Python Imaging Library (PIL), in collaboration with colleagues Simon Lin and Brian Chamberlain. Simon has written a blog entry on this work. Above is the caption which accompanied our submission.
