I write code that generates images like the ones you can see below. Some of the algorithms will let me create images as large as 400 megapixels. This means that you can print images as large as around 1m x 1m. Have a look, and let me know (e-mail, @shall_be_lifted, facebook) if you would like more information, or if you would like me to generate a high resolution image for you. I can provide you with an image file that is ready for print. The price will depend on which image you want, and on the resolution you need.
