Heavily inspired by Oldstench's "New desktop image", below, which I really
liked a lot.

I did some postprocessing in photoshop to improve grainy focal blur and fix
some reflection issues. I didn't mean for the reflection to look bumpy, but
I sort of liked it a little so I kept it mostly.

Nice, sometimes "simple" is the most effective!

Pretty too ! Look's like sort of blood drops floating in a outer-space
atmosphere... I don't know exactly how to say that with my poor English...

Very cool! I am flattered that my pic inspired this. 
Just curious...I assume that your spheres are placed randomly; how is
it that you get them to not intersect with one another?

I keep an array of sphere positions, and each time I make a new sphere, I
check the new position against every previous position in the array, and, if
they're too close, I choose a new position. This gets really slow for large
numbers of spheres, but I had few enough that it wasn't a problem. After
that, it was just a matter of choosing a random number generator that
produced a good result.

I used a more complicated (but similar) technique in
http://www.slimeland.com/images/pictures/ManyReflective.jpg , where the
spheres could have different sizes, to keep them from intersecting. There
were so many spheres in this image that I had to make an array of positions
beforehand, sort them, and compare them against each other (using the
sortedness to reduce the number of necessary comparisons). This gave a
nearly complete list which I could use as a beginning for placing the rest
of the spheres.

Thanks =)

Your statement made sense; I'm not sure what you were unable to say.

I had thought that it might have used an array, but I was unsure. Now
I know where to begin.

Sweet! Plagurarishnessism is the most sincere form of flattery :-)
