Since Microsoft PowerPoint has become the dominant scientific meeting presentation format, my collection of right-left stereo slide pairs has basically been rendered obsolete. Yet, contained within these striking images are valuable scientific data. This communication describes an easy method whereby analog slide data (i.e. scanning electron micrograph RL pairs, Figs. 1 & 2) are transformed into an electronic format such that the need for projector polarizers is replaced by inexpensive red-green or red-blue 3-D glasses.
