The Null Chamber - Greg Egan

"The Null Chamber is a cavern in the Splinter that contains a part of the Null Line, the line traced out by the orbit of the Splinter, where objects are perfectly weightless. Using the applet above, you can re-create the experiments that Zak and Roi conduct in the Null Chamber, and try out new ones of your own. The directions within the Splinter are:

garm = closer to the Hub (the unknown object that the Splinter orbits) / sard = further from the Hub;
rarb = the direction that the Splinter orbits / sharq = opposite the direction that the Splinter orbits;
shomal = above the plane of the orbit / junub = below the plane of the orbit."
