I have just found this site and thought some of you might be interested or even had children who might be interested here is the link http://www.stellarium.org/
I do like astronomy,together with my daughter we are both of the arm chair type. Or reading mags or looking at programs on t.v. So when looking at a web site like the one you put up,very nice though it is,reading through some of the comments it seems like one needs the brain of a planet. Never the less it`s a good find.
