Friday Fractal: Warning
Warning When I am an old woman I shall wear purple With a red hat which doesn't go, and doesn't suit me. And I shall spend my pension on brandy and summer gloves And satin sandals, and say we've no money for butter. I shall sit down on the pavement when I'm tired And gobble up samples in shops and press alarm bells And run my stick along the public railings And make up for the sobriety of my youth. I shall go out in my slippers in the rain And pick flowers in other people's gardens And learn to spit. You can wear terrible shirts and grow more fat And eat three pounds of sausages at a go Or only bread and pickle for a week And hoard pens and pencils and beermats and things in boxes. But now we must have clothes that keep us dry And pay our rent and not swear in the street And set a good example for the children. We must have friends to dinner and read the papers. But maybe I ought to practice a little now? So people who know me are not too shocked and surprised When suddenly I am old, and start to wear purple. Jenny Joseph |
I just found this wonderful poem today. But since it was written in 1961, you probably already know it. What a delight it is. . .

Friday Fractal: Nautilus
This is my fractal flame creation in Apophysis 2.09 (the version for Windows 7 which renders hours faster than version 2.02). I used a tutorial that I found. After hours of manipulation, I was satisfied with this helix (a type of space curve, i.e. a smooth curve in three-dimensional space. It is characterised by the fact that the tangent line at any point makes a constant angle with a fixed line called the axis Source: Wikipedia).If you use Apophysis, it will serve you well to use the tutorials that are available. Fran's Tutorial is great for version 2.02 and offers a lot of basic information.
Below is my very first Apophysis (2.02) flame. I call it Laughing Penguin.
I found a series of six Arthur C. Clarke videos about fractals, The Color of Infinity, on YouTube. This week I'll feature the first 9 minute video:I will no longer link to the Macintosh OS X fractal flame software, Oxidizer. If you need information for it, click on the "fractal flame" tag at the end of this post. I hope you try your own fractals or flames and join us on Friday Fractal. I would enjoy having enough participants to justify using Mr. Linky! Thank you for stopping by.

Friday Fractal: Fractal Trace on GIMP
I think it was a mistake for me to begin learning fractal software on Windows in February. The weather is great and I should be outside doing all sorts of stuff. But here I am playing fractals. I saw a reference to using a fractal trace filter on GIMP so of course I immediately had to sit down and play with it. Above is a photograph of jewelweed (also called spotted touch-me-not) taken on our Butterfield Pond hike in August. I used the map filter fractal trace and obtained the image below. I like the self-similar frame created by the filter.
I then chose another jewelweed photo and used the filter again:
Clicking on any of these images will open a new browser window and display a large photograph.
And finally I chose one of my favorite sunflower photographs:
I accepted the default settings for the filter on each of these photographs. There is a snowstorm coming next week (hopefully) so I will spend the snow day playing with the filter and other fractals some more. I find these GIMP and Photoshop filters to be a good way to enhance poor quality photographs (the second original jewelweed photo is not my best) and turn them into something interesting.

Friday Fractal: Nova: Hunting the Hidden Dimension
Now that I have the Internet again, I have a lot of blogging to do. That's why there are two Friday Fractal posts tonight. Hunting the Hidden Dimension is the perfect introduction to fractals. You can watch this PBS video online now by clicking the link on the title. There is another PBS site, the Hunting the Hidden Dimension homepage, where you can explore fractals with an interactive applet and even create your own (as I did, above).If you are a teacher, you will find a teacher's guide with an interesting classroom activity. You can stream the program for free on a projector at school, do the activities, let your students lose with free fractal software and see what happens! I'm going to suggest this as an After School Program at school.

Friday Fractal: FractalWorks: Fractal Diamond Wiki Colors
Download the newest version of FractalWorks, then join the Flickr FractalWorks Group. This is a 3-D fractal rendering. If you have the new FractalWorks installed on your Mac, click on this Fractal Diamond link, then click on the link underneath the Diamond and your FractalWorks will automatically open and render the Diamond. I have done it and it works. I haven't created my own fractal yet. I bet you wish you got a Mac!
