That's the algorithm - just hold the 'i' key down for as long as you like!
The suspension is elastic - not wires. This is my attempt to firstly free the Sliiiiiiiiiinky from the constraints of gravity and secondly unite a small number of Slinkies, or rather create some subset of the one true Sliiiiiinky, since the factory insists on chopping Sliiiiiiiiiiiiiiiiiiiiiiiiiiiinky into such short fragments.
Yes, they should do this in the new Space Station - it would be a lot easier than all those elastics!
I don't have any audio samples on the site, but now that techie slashdotters are perusing it, perhaps I should. Sending an impulse at one end - by tapping with a coin - generates a short pulse of all frequencies. The high frequencies travel faster than the lows, due to some effect of the stiffness of the steel. (This is apparent at the 0.5 to 5 Hz range of the big visible waves too.) At the other end, a piezo pickup gets a "chirped" sound, a high tone rapidly descending to a very low tone. It sounds just like a swept oscillator. Since I figure no-one else has 645 metres of wire = 2,116 feet suspended in a way which supports vibrations of frequencies almost from DC to daylight, I figure I could get another gong in the Book of Records for the world's most serious *chirp*.

Stairs are boring by comparison - Sliiiiiiiinky enables anyone at all to make transient three dimensional kinetic public art - and there's no electronics involved.

Longest Slinky / Longest Staircase / Big Problem! (Score:4, Informative)
When your slinky has finished unspooling off the top step, its rear coils then swing over the top of the slinky to fall on the next step, this after a point will preclude an indoor venue due to the height clearance required. The Pyramids may be the only option.
As slinkys get longer, they also fall over more than one step at a time (I know they shouldn't but its something to do with rigidity) - Is this cheating?
And finally, very big slinkys with small diameters (across the coils) become unstable (I know; I'm a muppet, but I just tried this:) and fall flat after the first step and slide to the bottom. So your longer slinky needs a wider 'foot'.
All in all, it make the challenge of creating the woulds largest working slinky look quite something

Earthcore [earthcore.com.au] NYE 2000 was a weeklong techno-marathon ... the sliiiiiiinky was there on a hill very similar to the one in the "space cadets" [firstpr.com.au] photos. It moved so gracefully on the elastic strings it's suspended by. A slight movement on one end creates a lovely fluid ripple along the length of the whole object. People creating ripples on both ends make waves that gently join each other. Very peaceful to look at.
Both Earthcore and the Sliiiiiiinky are not to be missed if one's in the Melbourne area!

Christian mentioned the DJ booth at that Earthcore party. Cat (my Devil Fish assistant at the time and Sliiiiinky co-pilot) and I were at an excellent smaller party at Nagambie on NYE, and we arrived at Earthcore on 2 January. People were raving about the big night! The main floor was on the top of a hill, with the DJ booth being the front part of an old Victorian Railways diesel loco. It is all made of 1/4" steel.
Some of the crew saw it on a truck going omewhere, and they spoke to its owner and hired it for a few weeks. Behind it is the very dry reservoir of Lake Eildon. Cat and I surveyed the scene. Two crashed light aircraft and a motor car tumbling on a horizontal axis were parts of the decor. A bulldozer doubled as a lighting stand . . . there were other huge sculptures. The thing on top of the loco cab is a ferocious tesla coil of a chap also called Robin. Apparently there were wires all over with sparks leaping around the place and people all said that that night, everthing just went **off**! The local fire brigade was on hand, since the place was as dry as buggery and was a real fire hazard.

Two ideas (Score:3, Interesting)
First off here's a simplification that anyone can try. In my high school physics class (many years ago ;-) when we were studying waves, one of our lab experiments was to go out into the tiled-floor hallway. With the help of a lab partner, we'd stretch out a slinky along the floor. We experimented with creating standing waves of different periods. This permitted experiments in the horizontal and longitudinal axes (though not in the vertical, which the sliiiiiinky also supports). So, try it at home!
Secondly, I have a suggestion concerning the tendency of the sliiiiiiiiiiinky to get tangled onto itself that was often mentioned in the article. Wouldn't an initial tensioning of the sliiiiiiinky reduce or event prevent that from happening? I'm thinking the use of some cords, strings, or bungie cords being attached to the ends of the sliiiinky and whose other ends would be attached to the endmost vertical support poles. The downside, I would expect, is that the wave would move more quickly down the length of the sliiiiinky.
