random number visualization

[mjrand]

Can anyone explain this to me?

How in the world was that image created by using the rand() function in MS Excel?

Why is that so surprising? The points are randomly distributed throughout the sphere. Except for their color, if that's what you mean....

 

[mjrand]

I mean the whole thing in general. The colour too. How can you even create images in excel?

If I wanted to make something like that in Excel, what would I type in?

I think its just a 3-d graph

X,Y,Z scatter graph! (i'm just guessing)

 

[mjrand]

Ok, but how would I make one of those myself?

*EDIT* Ok I found this page with instructions in the bottom sort of. http://casoilresource.lawr.ucdavis.edu/drupal/node/371 It's some kind of code. What do I do with it?
