Picture of the day
Stereoscopy
Stereoscopy is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision.

This image of two Passiflora caerulea flowers is arranged as a stereo image pair; it can be viewed stereoscopically by using the cross-eyed viewing method (parallel version here).Photograph credit: Franz van Duns
