Hi all,

Not likely as "random" as one would think.  Better than nothing as
well.

 
Well, why not as random? I think you can't generate the same mouse
movement twice, right?

 
Depends on the mouse, I'm afraid.
 

And how could we call that?

 
A good start, but you'll want to mix in some bits from somewhere else.

 
Thanks. Done. You may check out the additional Linux code.

If you are on Linux, you already have a much better randomness
generator in /dev/urandom, which not only takes input from mouse, but
many other I/O devices as well, to 'mix up' the randomness.

You are unlikely to gain higher quality randomness on Linux with just
some code to watch the mouse.
