Hi all,
I want to draw some paths that won't intersect with each other

100 circles without any intersections. I use a very stupid

That is easy to answer: you can't (well, not unless you invest a *lot*
of effort into creating a bitmap edge structure).

For circles, probably lua calculations will be faster because the

Thank you all guys,
To Aditya: Clearly I over-emphasized the randomness. Actually, what I
meant is a little more complex: identical objects on random
coordinates and they don't intersect with each other. We can rotate
them but we can't re-size them and scale them. Your code is very
interesting.

Both Taco's and my solutions can be adapted so that you do not randomize the
radius. (Taco's solution will also work for arbitrary object that can then be
rotated by a random amount).
Here is another idea. Ask metapost to test for intersection, but
