Work and Teaching Featured in Seattle Times

Critique in my Sensing and Control Class (DXARTS 470)

DXARTS (and my work and teaching) were featured in a long article by Seattle Times arts critic Michael Upchurch which appeared on the Sunday, March 23 issue of the Pacific Northwest Magazine.

On a purer visual-arts front, “Convex Mirror” by graduate student Robert Twomey created highly roboticized images earlier this year in a street-front window on Amazon’s campus in South Lake Union. The piece used a CNC (computer numerical controlled) plotter, a 180-degree circular fish-eye lens and some custom software to produce its result.

A gel ink pen was fixed in a housing that was suspended on two strings against an acid-free mat board. Computer-filtered input from the camera guided the pen’s bobbing progress across the mat board. The result was a study in duration and evanescence. The building across the street was drawn in sharp detail. Passing cars and pedestrians registered as mere wisps, if that.

Explaining Convex Mirror drawing
Abe King, a student in Robert Twomey’s Mechatronics class, sets up a class project with an inverted image of himself from a webcam projected on the wall.
Jake Garrison, a student in Twomey’s Mechatronics class, looks at a prototype for a 360-degree interactive camera made by students Tia Zweber and Calder Danz for a critique in the class. The camera burned out at the last minute, but was meant to be housed in the box made of two-way mirror material, and triggered by an accelerometer.
