This is a different breed of time nuttery than usual in this list but i
think that at least some of you will enjoy it:

The really scary thing is that this is some sort of postgraduate thesis
project examined by a swag of learned doctors, complete with the "artistic"
waffle of What It All Means.

Accuracy depends on the stepper motor driver :-)
A really neat conceit!

That is just ... cool. But I thought of a way to do the same thing without
the rope and mechanical parts. I figured I can replace the ropes with rows
of LEDs. Then I can turn on the LEDs to simulate the white rope and turn
them off to simulate the black marks. Now you don't need the bearings and
stepper motor. Pretty neat idea, huh!

An enormous amount of work went into painting the pattern on that rope too.

A cleverer approach would have been if there were multiple shorter rope
loops...  Or geared ropes.

I think the realization that it takes thousands of feet of bit-serial
crafted rope, is part of the art. Just IMHO.

Something like the "core rope fixed memory" of the 60's,
http://en.wikipedia.org/wiki/Core_rope_memory

Many industrial machines internally still emulate the "infinite paper tape
loop" concept from 50+ years ago when CNC was new. Young guys who have
never programmed that way may not appreciate how programming with zero
cleverness is in itself clever (making it far easier to predict performance
etc. even though the performance is going to be low.)
