I've put together a short program to calculate the proportion of an 
arbitrary grid of (x, y) points that lie within a given distance of the 
origin and thereby calculate pi. It surely isn't efficient but seems 
intuitive to me to do it that way and so easy enough to do. Before it runs 
into overflow-errors, it comes up with:

3.141592653589766 < pi < 3.1415926575897664

It'll be interesting to see on the various methods suggested in "pi 
Unleashed".
