Here is a 3-D view of the eggs of the Cabbage White butterfly. You can view the stereograph by:

1. Using the Cross-Eyed method.
2. Using 3D prism glasses (berezin.com/3d/3dprism.htm)
3. Using Brian May’s OWL Stereoscope (londonstereo.com)

I took the images of the Cabbage White butterfly eggs using a Canon 5D MkII DSLR and a research trinocular microscope. The 2 images are focus-stacked using the Helicon Focus software, and Dr. Brian May created the stereograph.
