Info: A figure eight knot.

The idea - and the basic design for this item came from this site:
http://www.lipsons.pwp.blueyonder.co.uk/mathlego.htm

Andrew, kindly supplies on his site a ldraw file for the knot - but it's build up in 1x1 bricks!

It takes a lot of work to convert it to an item, which will work in 'real life'.

I built it from brown, because I wanted to use it in a town layout I was building for a media project 

(school) - (children’s storybook), this way it would look like those metal sculptures you see in places!

Brown = bad choice! Hard to get (at the time) expensive, and rare in certain types.

Thanks

Troy
