I have installed various versions of a piece based on the knot tightening movies available elsewhere on this webpage called Everything in its Right Place in the Contemporary Mathematical Photography and New Media Exhibition at the New Image Gallery of James Madison University, in the final show of the Math and Art summer program in 2004, and at the Joint Meetings of the AMS, MAA, and SIAM in 2005. I don’t have a good photograph of any of these installations, but the photo at left is ok. I’m not showing this piece anymore, but you can see the color version and the very high-resolution color version.
