Well, not exactly "you" as such, but maybe your children.
Some tribes are known for lengthening their necks by
wearing rings which slowly stretch them over many years,
starting during childhood.
I propose to apply this principle to the optic nerve. At an
early age, a small ring is fitted
around the nerve at the
point where it joins the eyeball. As the child ages, more
rings are slowly added, until the day occurs when the
eyeballs can be popped completely free of the skull.
At this point the rings are removed and replaced with a
short section of the "gooseneck" material used for
microphone stands. This section continues to be gradually
lengthened over time.
In this manner, once you reach adulthood, you will have
fully-fledged eyeballs on stalks!
The many practical benefits of this idea include:
- The ability to look in two directions at once.
- The ability to bend your eyes completely round to the
back of your head, just so that you can have eyes "in"
(kinda) the back of your head.
- The ability to point your eyes directly at each other, so
that you can look yourself in the eye without needing a
mirror.
- For the fashion-conscious, the endless potential for
accessorizing by clipping all manner of glitzy LED-
illuminated thingies to the stalk just behind the eyeball.
- The promise of do-it-yourself colonoscopies.

I'm amazed no one's already done this |
|
| |
I just wish someone would invent some automatic capture device which could be put on stalks instead of my childrens' eyeballs. |
|
| |
This is possibly the best idea ever. |
|
| |
I forsee a couple of problems with this. |
|
| |
at the same time, lengthen the tongue for cleansing the eyeballs. |

The nerve of some people... |
|
| |
I would think the optics on this idea would be poor... |
|
| |
I wonder what the baud rate of the optic nerve is,
and how much signal delay an additional few inches
would be. |
|
| |
I can't see this catching on. |

Time to add another ring? |
|
| |
She's probably never been in a Turkish prison, either. |
|
| |
Don't those women actually end up with lowered shoulders instead of elongated
necks? |
|
| |
// I wonder what the baud rate of the optic nerve is // |
|
| |
8.75 Mb/s for guinea pig [1], ~10 Mb/s for human [2]. |
|
| |
// how much signal delay an additional few inches would be // |
|

That obviously depends on how fast the signal travels. In red-eared turtles, it's 1,
3, or 13 m/s depending on axon diameter (with different diameters going to
different places in the brain and presumably carrying different types of data) [3].
In rats there are also three groups of axons, with the faster of the two conducting
at 5.4 and 16.8 m/s in normal rats, vs. 5.8 and 10.3 in rats given a low dose of
lead early in life and 5.2 and 9.4 in rats given a higher dose [4]. Also, apparently
it changes with myelination, which itself changes based on what visual stimuli the
eyes are exposed to [5]. |

This idea could go very well with the one
encouraging you pr brain cells to grow outside of
your skull. Consider the volume taken up by your
eyeballs and how much additional grey matter that
could yield, with a ready-made access port. |
