On a close-up view, you can see on the left face, an angry man and on the right face, a woman with a neutral facial emotion. But step (much) further back, the faces change expression and even genders! if you squint, blink, or defocus, an angry man should substitute for the face of the woman and the left angry face should not be angry anymore.

This impressive illusion created by Dr. Aude Oliva and Dr. Philippe Schyns, illustrates the ability of the visual system to separate information coming from different spatial frequency channels. In the right image, high Spatial Frequencies (HSF) represent a woman w69, 243-ith a neutral facial expression, mixed with the low spatial frequency information from the face of an angry man.

The above two ambiguous faces, termed hybrid faces, are published in the journal Cognition, 69, 243-265, 1999. Elsever publisher

Camden Maine. Labor Day 05
2005, October 24, Monday, 21:38
Radha just put together the album from our weekend in Maine.

We went to Camden, Maine over Labor Day weekend. Completely unbeknownst to us it was the 11th annual Windjammer Weekend where the festivities were held at the harbor right across the street from where we stayed.





The nifty album software was written in Perl with a smattering of Javascript by Radha.
