Just posting the link here for those that are interested. I learnt a lot about the 4P in this project! I also wrote a little demo program which you'll see if you scroll towards the bottom of the blog page.

Yes, it's not an article as such...rather a series of regular updates as in keeping with spirit/requirements of Retrochallenge. Quite time consuming to put all the details down but it does show the reasons behind decisions. This can be useful when you think "Now why did I do that?"nama wrote:Congratulations!!!
