The second of the exceptional root systems, smaller than E8 but no less precise. 126 roots, 7 orbits of 18, every connection exact. More open than its sibling - the underlying structure is easier to read.
About this print
About this print
E7 is the second-largest of the four exceptional root systems, sitting between E8 and E6 in a family of objects with no straightforward lower-dimensional analogue. It has 126 roots in 7-dimensional space, each one connected to 32 others at the nearest-neighbour distance, giving 2,016 edges in total.
The Coxeter plane projection collapses all 7 dimensions into a single plane while preserving the system's 18-fold rotational symmetry. The 126 roots arrange themselves into 7 concentric rings of 18 - a structure that is genuinely visible in the print in a way that E8, with its greater density, makes harder to read. If E8 is the overwhelming one, E7 is the one you can actually study.
The Signature series
The Signature series
Signature is a collection of mathematical, scientific and infographic visualisations - prime number distributions, evolutionary trees, geological timescales, and other structures that become something unexpected when rendered at print scale.
Each piece begins as a data-driven computational process and is developed into a finished artwork through a combination of custom code and design refinement. The aim is not to illustrate mathematics but to make the underlying structures visible - to find the image that was always inside the data.
The series draws on fields including number theory, evolutionary biology, palaeontology, topology, and information design.
Paper and printing
Paper and printing
All prints are produced to order on 250gsm archival matte paper using pigment-based inks, chosen for colour accuracy and long-term stability.
Each print is rolled in acid-free tissue and shipped in a rigid cardboard tube, sealed for moisture protection, ready for framing on arrival.
