I've been building a few dynamical models for the new "space webs" reseatch project I've been working on
, the result is below:
http://www.mech.gla.ac.uk/~dmckenzi/ariadna/Space-Web-Model01.html It's a really nice piece of kit called
LiveGraphics3D that takes a Mathematica picture and lets you rotate it and generally see about it in all directions.
I built a model of a hinged model orbiting the Earth, the red branch is pointed away from the Earth, and the blue and green branches are pointed towards (ish) the Earth. The animation on the lower half shows what the motion would look like if you were to follow the structure while orbiting in space in a flying saucer a short distance away.
