@MichaelHale I succeeded writing symbolic method for (low) dimensions for average distance between points on hypersphere, thanks to v9 CoordinateTransformData... but if I ever want to show it, I have to clean it a bit :)

The voting culture on math.se is awful. It seems, due to the pure mass of questions they have, no one really votes. It would be nice if someone would give this answer a vote, because it helped me a lot.
(You don't have to upvote my question! But the guy extended his answer after I asked him and I believe one vote and the accept from me is just ridiculous)

I wouldn't dare to go voting there - I'm pretty clueless on actual maths, 90% of the time. I don't know if such limitations prevent others from voting, though...

There was a question here on plotting the image of a 3D plot on the box surfaces. I can't seem to find it. Any help would be appreciated.

Q: How to make a drop-shadow for Graphics3D objects

cormullionWhat's the best way to make a drop shadow for a 3D object? image = Graphics3D[Sphere[], Boxed -> False] I can get a blurry black outline of this: imageShadow = Blur[RegionBinarize[ColorNegate[image], (* bottom left corner --> *) {{1, 1}}, 0.1], 20] which could act as a good shadow:...

All, I've set up a community event here in the main room tomorrow (Friday 13/9) to celebrate our 10,000th question. Time to hang out, banter, answer all those unanswered questions and generally celebrate what we have achieved with this site.
