This video introduces us to his thought process, and we get to meet his parents. Mr. Wilcox wrote a book called Variations on Normal illustrated with his comic sketches.
|Dominic Wilcox's Binaudios for magnifying faraway urban sounds|
Edit: Frank Palmer sent this photo of "WWII acoustic aircraft detection system similar to that of Dominic Wilcox’s “Binaudios” but pre-dating him by about 75 years. These were used by the Brits, Germans, Japanese and others early in the war before the detection of enemy aircraft was taken over by radar."
Here's Wilcox's website.
(Thanks, Bryn and Frank!)
