Shutter - You can make any regular polygon out of identical triangles and you can make any straight-sided shape at all out of triangles if they don't all have to be identical.

I like messing around overlaying triangles to make regular shapes and in the course of doing just that, I came up against a puzzle. Was it possible to go from the first shutter shape to the second, just by moving the narrow point of each of the 12 triangles one corner clockwise around the 12-sided polygon. It looks obvious but in fact it's impossible because to get the second shape some triangles have to be both above and below their neighbour.

So the second shape is a cheat - it's not 12 triangles but 24. But no less fun for all that.

Designed by David Lawrence, d/dx art prints are created on 315 gsm Canson Infinity artboard produced at the centuries-old Arches paper mill in France. This superb artboard 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 board makes DIY framing a simple matter.

The prints are standard European A4 (210*297mm) or A3 (297*420) 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.

Additional

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.
