Seeing through the eyes of a butterfly


Caption for the images above, from the weekend Wall Street Journal: "A photo of a Great Spangled Fritillary butterfly. The grainier images show a simulated compound-eye view of how one butterfly would see another from different distances. At 18 centimeters (7 inches) โ€” the view at top right and the typical courtship distance for the species โ€” if either the eye or the butterfly moves slightly, large portions of the image flash back and forth between all orange and all black."

For further reading: "What Is It Like To Be a Bat?," Thomas Nagel's classic 1974 Philosophical Review essay.

I would pay plenty for an iPhone app that let me see the world as a dog, cat, horse, lion, butterfly, spider, etc. sees it โ€” and I expect I'm not alone.
