It’s fractal art! We are big fans of the genre and actually enjoy creating our own fractals, too. Fractals are basically simple mathematical equations that, when you apply some complex coloring algorithms, often reveal some complex and very beautiful designs. At their heart, fractals explore the concept of “self-similarity”, 
which means that you can “drill-down” into the image forever – and continue to reveal ever evolving designs that maintain the character of the original image. Please enjoy – and right now all images are… free! So, help yourself to a copy and use it for your computer wall paper! If you enjoy these images, there is a link at the bottom of this page to a gallery of additional images. Be sure to click on any image to get a larger view. Thanks! And let us know what you think –
