>From the web page: (http://www.lsw.uni-heidelberg.de/~rwichman/Nightfall.html) "Nightfall is an astronomy application for fun, education and science. It can produce animated views of eclipsing binary stars, calculate synthetic lightcurves, and eventually determine the best-fit model for a given set of observational data of an eclipsing binary star system." It is GPL'd. If no one has already done this (I can't find it in the archives) then I will upload fairly soon. -- Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us!
