This cheerful, busy design is inspired by the work of Georges Louis Leclerc, Comte de Buffon, who published a paper in 1733 offering a solution to a tricky problem in probability. The simplicity of the design belies the fact that an experiment with nothing more than a needle and some lines on a piece of paper is capable of providing a fair approximation of the mysterious value we call 'pi'.
The story behind the design and an explanation of some of the mathematics can be found at http://ddxart.co.uk/pi-sticks/. (Copy the address and paste it into the address bar of your browser - unfortunately Etsy descriptions can't contain direct links).
Designed by David Lawrence, d/dx art prints are created on 315 gsm Canson Infinity Museum Rag produced at the centuries-old Arches paper mill in France. This superb art paper is acid-free and uses no optical brighteners to degrade over time. Ultrachrome K3 inks provide vivid colours which will last without fading for many decades in normal conditions. The robustness of the paper makes DIY framing a simple matter.
The prints are standard European A4 (210*297mm) in size and are unframed. They are packed flat in crystal envelopes with cardboard stiffener and posted in a rigid container via Royal Mail first class.

The colours you are seeing on your monitor are inevitably not precisely the colours you would see if you were looking at the same design in printed form. There is simply no way around that, since the internet places limits on the range of colours that can be displayed and, even if that were not the case, every monitor is subtly (sometimes wildly!) different in the way it displays colours.
But you can be reassured that the quality of our equipment is such that colours and quality are consistent over time and the print you receive will be identical to other prints sold in galleries and art fairs to buyers who have every opportunity to handle and assess them.
