I must confess that I am an addict. I have become addicted to creating computer-generated images. Having recently posted about Processing and Oxidizer, I have found another image generator called “Context Free.”

Context Free “is a program that generates images from written instructions called a grammar. The program follows the instructions in a few seconds to create images that can contain millions of shapes.”

Creating images with the software is a piece of cake. One can download from a gallery of “grammar” files or create your own scripts. Downloaded scripts can have their output modified by entering a three-character code into the Context Free application, leading to millions of permutations of the work.

It’s a fascinating program to play around with and some of the output is simply stunning.

Best of all — the software is free, open-source and is available for Windows, OS X and various flavours of Unix.

An open-source replacement for .mac services.

An Internet notification platform that works on both Windows and Mac (including support for Growl). “Using Stitcho, your website can send real-time notifcations directly to a user’s desktop, even when their web browser is closed.”

Having read Smashing Magazine’s recent article, “35 Phenomenal Fractal Art Pictures” and being stunned by the images presented within, I wanted to have a go at creating my own fractal flame image.

A quick Google led me to the free OS X software, Oxidizer. A few minutes of experimenting and I was soon creating great fractal images of my own.

It’s great fun and I highly recommend you give it go. Post your best images in the comments.
