It's not as advanced as Daloze's solution, and it definitely can (should?)
be enhanced, but my solution is available at http://gist.github.com/447554.
Any feedback is welcomed.

In a nutshell, Point.random implements a random algorithm that
basically repositions the head of an initial null vector v until it falls
within a circle of the given radius that is centered around the origin. It
then translates a copy of that head to the correct position with respect to
the given center.

BTW, this is the first time I participate in the Ruby Quiz. I'm looking
forward to future quizzes :)

Regards,
Yaser Sulaiman
