Thanks for the heads up,  I've made a simple version of the clusterer
which you can view on pastebin: http://pastebin.com/7HmAkmfj If you have time to look through
my code I would be very grateful!

I had a go at implementing something along the lines above and I'm still
getting very bizarre results. There does appear to be some sort of logic
to it though, if you look at the graph chart, you can see that It seems
to be doing the clustering right and then forgetting to remove the old
groupings providing this "cloning" effect for some cluster groups.
