This site is a catalogue of my art. It is a sampler of my pictures. There are many more. The pictures here are organised into families and have individual names below them. The families may be conceptually related or be colourways of one design. They are, more or less, in reverse chronological order.
Scroll down and click on any picture to expand it a bit.
For bandwidth reasons most of the pictures on this site (except the Anglesea & Universes sections) are in JPEG format. This means a loss of detail over the original renderings.
All prints made are part of a limited run of 500 for each picture. A numbered certificate of authenticity is included with each print.

To preserve the smallest details prints are rendered to 300dpi in a non-lossy format. Prints are made, generally to one size, on paper of at least 200gsm. They are in top-quality, fade resistant pigment ink.
Contact me via email and we can discuss your requirements.

media & prices

The latest Eco-pigment inks are used in my prints. They are fade-resistant but should not be exposed to direct sunlight.

The paper I use is 200 or 260 grams per square metre. It has a smooth satin and highly opaque white finish and is suitable for indoor use.

Prices are usually specified next to individual pictures. Post and packing within the UK is included in the price.

If shipping outside the UK is required please email me and I will investigate individual cases but the cost of shipping abroad will include insurance.

my fractals
A fractal is a design in which the larger parts are made of a collection of smaller parts of the same general appearance. The smaller parts are made of tinier parts... And so on ad infinitum...

For my purposes pictures are generated by a series of seven 'algorithms'. An algorithm is a set of mathematical instructions. The instructions aren't complicated but they have to be worked out millions of times to render large pictures. Fortunately I can program a computer to do the sums for me.

size and rendering
One interesting thing about fractals is that the bigger you make them the more detail you see. Its not like a photo where if you make it too big all you get is a blur.

So the bigger the better with fractals. It just takes longer to create (render) them. This is because each point (pixel) of a fractal has to be calculated. If you have a 4300x2000 pixel picture, not uncommon for me, thats 8.6 million pixels. Multiply that by seven algorithms each containing 10 elements and you get 560 million calculations! So the more pixels you have the more the old computer has to sweat. I once did a 10 metre by 5 metre render just to see if I could. It took three days with a computer doing nothing else. Thats to do something the size of a double-decker bus. Though if you put Mr Throbbe on the side of a double-decker bus you'd probably get arrested.

They'd certainly see you coming.

The upshot is with modern computers and printers there is no practical limit to size of fractals. It just takes a bit longer.

I have a 'full size' picture on Wikimedia Commons for inspection. Its in PNG format and is a 19MByte download.

aspect ratio
Some of the designs shown here can easily be rendered in other aspect ratios to suit different projects.

In the 'art' series of images this is not always the case.

The reason is that all my renders are just that. There is no post-processing or Photoshopping to try to make them look better. The renders are limited by what the algorithms produce and I try to arrange them to best effect. This means that just 'off-screen' may be a blob of something which upsets the balance of the picture. So I'm kind of stuck with what I get.

I am primarily concerned with earning money from larger prints of my works onto paper and plastic. From paper size A3 and up. Small prints for personal use or pictures for use as PC desktops may be downloaded from this site and used freely. I'd be grateful for attribution and donations though.

For an exhaustive list of products checkout the links below. Possible product materials include, fabrics, ceramics and plastics. Durable and striking results can be produced on all these surfaces.

The 'product designs' here are in sets of six colourways. From these a set of six identical or six different but themed products may be made.
