I think this ranks in the stupidity stakes with the 1950s/60s Project Orion proposal for blasting a manned spaceship into orbit by exploding hundreds of atomic bombs underneath it:

For the cruising hordes of slashdotters, I scrambled some audio files and frequency analyis and have added these to the site. This includes analysis of a chirped impulse response which spreads the frequencies out in time over more than 2.5 seconds.
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.
A friend made me promise to contact the Guinness Book of Records about Sliiiiiiiiiiinky. I haven't done so yet. James Industries - who have manufactured the Slinky since 1945 - say they don't know of anything like it.
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*. Let me look around and see if I can put a.wav on the site soon. In the future, there will be some video too.
Stairs are boring by comparison - Sliiiiiiiinky enables anyone at all to make transient three dimensional kinetic public art - and there's no electronics involved.
Sliiiiiiiiiiiiiiiinky may be having another outing at Beckett Park in late March or early April - write to me if you want to come.
As for the favorite photo of the Space Cadets, this is part of a page http://www.firstpr.com.au/slinky/tourism/ Well gents, isn't true that so much of our efforts go, ultimately, to keeping fabulous women smiling and gyrating? Ms Yellow Cadet worked at a computer shop and now is one of the organisers of Melbourne's best trance techno outdoor parties. Ms Blue Cadet worked on a very high floor of some god-awful city building, for a *bank* of all things. I hope she has transformed since then. . . . . . . and fellas, when it comes to this particular approach to getting girls gyrating, mine's longer than . . .
