Fascinating

What is missing from the story is the optic nerve.  Do these 'anywhere' eyes connect back to the brain ? That would be a really neat trick.  However this is amazing :

They can make an 'eye' form anywhere on the body.

"But the electrical signal can trigger eye development almost anywhere, indicating that the membrane potential somehow supersedes molecular information for telling a cell what to do."

“The thing about this that is so cool is that the eye is thought of as the epitome of a complex structure,” Coffman says. “The fact that a narrow range of voltage is enough to specify an eye is kind of amazing.”"

When they get to the point of making the eye extrude itself on a stalk, my husband will run screaming for divorce court.  I've tormented him many a time wishing for eyestalks.  (You can peek around corners, what's cooler than that?)

This sounds like it's in the same category as Scott Adam's The Dilbert Future where he predicted pranks by sealing each other's butts shut with the kind of instant suture device that they had on Star Trek.

Wow. The most interesting things I have read in a while. Thanks!
