Yeah, my wife lost the credit card and had to get it replaced, and I
forgot to update the host. :-P
It should be back up tomorrow afternoon.

Thanks Ron,
I'm working on a dynamic portfolio component
from a practical standpoint, something like this should work, it's
difficult to be sure at 5:30 in the AM.
get a random number from 1 - 10
var ranNum:Number = random(10)+1;
now if ranNum is less than 4 pick a random position within x of the origin
if ranNum is 6-8 select a random point within x
I was surprised that the squaring gave you any kind of banding since it
should be a smooth bias.
I think that the log transformation will give you less of a bias toward
one side but I have not pulled out all my old stats and calculus books
to check this out.
It would seem that a normal
Thanks Ron,
I'm working on a dynamic portfolio component for a client and I've been
given static designs that I have to match.
The beginning of the portfolio has a couple hundred *tiny* icons that appear
spread across the stage in a non overlapping random pattern. Thing is, it's
not a normal

Here I go answering my own question.
To make it more dense toward the origin, use {x,y} = {random[]^2,
random[]^2}--squaring the independently generated numbers (random[]*random[]
won't work). The result is a distribution with a sharp cusp at the
origin--the probability is a maximum there, and
Would a formula based on logarithms give you what you want as well?
You were not very specific about what you wanted the distribution to
look like.

Hi Ron,
Thanks for jumping into this thread amongst the tumbleweeds. Yes, I suspect
something logarithmic could work but don't know where to start. I am trying
to distribute 1000 particles randomly in a rectangular distribution area,
with a bias towards one side of the rectangle.
