I don't know, but here's one by way of StereoLithography http://emsh.calarts.edu/~mathart/sw/klein/Klein.html

Sorry, links are fixed here: If you are really interested in the technology of rapid prototyping and would like to learn more, goto: http://www.prototypemagazine.com/ And Yes it's possible to build a "Klien Bottle" http://emsh.calarts.edu/~mathart/sw/klein/Klein.html Full color parts and moving assemblies, http://www.zcorp.com/Solutions/Rapid-Prototypes---CAD/spage.aspx, Transparent, Opaque, Elastomeric, Rigid, Plastic, Metal, Ceramic, Wax... Allare available as a service from a prototype house somewhere in your area. http://wohlersassociates.com/service-providers.html All you need is a good solid or surface model to work from. I spent 14 years in the RP business, just about anything is possible, it just costs $$$.

I stumbled across this project 5 years ago & was immediately in love. The scope of the project is amazing, the engineering that went into some of the pieces is incredible, and the final product (the first prototype) was gorgeous. I read everything I could about it & even had it as my wallpaper for a while. If you like mechanical devices, take some time to look at this project - it's well worth it!

Currently, you can find the project's web page at http://www.longnow.org/projects/clock/

The mechanical computer, the solar synchronizer, and the power mechanism are all very cool pieces of engineering. However, the most fascinating part of the entire clock is the "Equation of Time Cam". A bit more information about the cam follows.

The proposed clock not only keeps accurate solar time (it resets itself every day at noon via the solar synchronizer), it also keeps accurate "clock time". How it does this is pretty amazing:

In general, when the sun reaches its highest point ("solar noon"), you can look at your watch & find that it's not really noon. On any given day, the variation between "solar noon" & "clock noon" is +/- 15 minutes. Of course, this variation chanages through out the year, following a well defined curve known as the "equation of time" (http://www.sundials.co.uk/equation.htm) (it looks like a 5th order polynomial equation).

So, when the mechanical clock resets itself at "solar noon", it's needs to account for this variation to determine "clock noon". One way to do this is to make a disc that is not perfectly round; it has a wider diameter at portions & a narrower diameter at other parts (something like a cross between a circle & an ameoba). This "disc" makes one revolution per year, and the variations in its diameter represent the difference between "solar noon" & "clock noon". So, at "solar noon", the clock resets itself & uses a feeler gauge on the disc to figure out how much variation to add or subtract to display "clock noon". So, assuming you have a sunny day every once & a while, you have a clock that will always have accurate clock time. Ingenious!

There's a problem, though: each year, the equation of time changes slightly. So, in order to keep accurate clock time for 10,000 years, you need 10,000 of these discs, each representing the distinct equation of time for each year. The Long Now foundation solves this problem by making an "Equation of Time Cam" - a continous stack of these cylinders. In my mind it is a thing of beauty - engineering at its best - well thought out and so simple. Here's a picture of the cam - it's the cylinder that looks like it melted a bit:

I hope everyone enjoys this project as much as I have - Have fun!

Well, it just so happens that one of my friends goes to the California Institute of the Arts where there's a professor by the name of Eddo Stern who has been doing this since the early 90's...he then cofounded C-Level in 2001.

(oh, and here's the link to the page with the date of his latest lecture at CalArts, just search for his name...)

What more can I say...

Also made by one of our siblings, and particularly useful due to the fact that it plays itself...

I think you are mistaken. WAV and AIFF are both compressed data formats.

Nope. AIFF encodes uncompressed audio samples only. There is a second format, AIFF-C that can contain either uncompressed samples or data from a variety of different compression formats.

WAVE format is comparable to AIFF-C, in that it can contain various types of sound data. But I think it's fair to say the vast majority of WAVE files are uncompressed.

Now that Would look like the WOPR !

Which is just what I have always desired, to complete my world domination plans ....

well the solution is obvious. find the hotest chicks you can find and change there grades for them in exchange for 'favours' ala wargames.

come on people dont you learn anything from the movies??

there are a lot of net.artists which works are hard to find in galleries, and who themselves (more or less) call net.artists and that dot makes the difference...

its work usually digs into political issues and specific issues of the media itself (net part of the net.art coin) rather then playing in the field of aesthetics and continuum of ugly and beautiful... media hacks are better thain paintings... just to start a little flamewar :)
