Alternative Implementations

I initially wrote spark because I wanted to play around with shell and some of the finer points of UNIX. It's been awesome.

That said, there are plenty of other ways to do sparklines, much of them shorter and simpler because they can leverage higher-level language constructs. Cool!

For those of you interested in trying out different implementations, have at it. If you've whipped up something cool, add it to the list below!
