It looks like an early form of the “bionic eye” will be arriving in the US.

I find these bits of science-fiction-turned-fact fascinating because of how they work.  They are, in effect, a simple bypass (okay, they are not “simple” at all from a technical standpoint, but the idea is simple, like bridging a crack in a circuit-board).  Which seems like it ought *not* to work, I mean, they are using the body’s own hard- wiring to do the job it was meant to, they just bypass the bit that’s not functioning properly.
