A while back I wrote a blog entry comparing various copyleft and permissive licenses and why I generally preferred the latter. In that article I explained how I felt copyleft could be useful, but felt that it was too far reaching. Since that time, I have done a lot of thinking, and I have come to a change of heart. Thus I am relicensing all of my content, as well as any future content I may create. I know this may inconvenience some people (all the better that I change earlier rather than later) but I truly feel that this is the best option for my work moving forward.
In this blog entry I attempt to explain how you can build a polynomial up from its roots. That is the points where the function equals zero. I then explain how this same technique can be used to build rational functions, and what this means in the complex plane. This is something I use to generate a lot of the abstract mathematical art that I share on Tumblr, Flickr, and Deviant Art. So if you are interested in duplicating my art style, or just reading the rest of my blog, this entry is essential.
