I saw this image the other day on Hacker News and Reddit : It’s a Game of Life pattern that prints out “Golly”. Neat, but I wanted my own. After about 5 minutes of playing around with the Golly logo pattern in Golly (a program for experimenting with the Game of Life), I gave up and wrote a program to do it.As a developer who was raised on procedural and object oriented programming languages like C, C++ and Java it took me a while to figure out what people were raving about when it comes to the benefits of functional programming techniques. I always thought closures and higher order functions were words used by snobby kids from MIT and grad students to show how overeducated they were as opposed to programming tools I'd ever find useful. This thinking was additionally fueled by articles like Joel Spolsky's Can Your Programming Language Do This?
Functional Programming in C# 3.
Background How do you get to be a great musician? It helps to know the theory, and to understand the mechanics of your instrument.

Anti-Aliased Line Drawing
First, let's start with an example to show why we want to use anti-aliased lines. The lines on the left are drawn with something like Bresenham's line algorithm. The lines on the right are drawn with an extended form of Bresenham's which anti-aliases. They are shown both at normal size and 4x zoom.List of algorithms
