Some scenes are problematic to photograph for one reason or another. They're too fleeting, or too intimidating, or too easily altered by raising a camera to them. Or perhaps you live in a country with silly laws governing what can or can't be photographed. In such situations I've often wished I could take a photo just by blinking. Wouldn't it be nice to push some magic button and capture the moment through one's eyes without the hassle of a camera?
If you've ever wished this, your dreams may be about to come true.
