Science-inspired art by Sienna Morris, drawn entirely with numbers and equations by hand. Based in Portland, Oregon, Sienna is self taught in science and art, and uses her Numberism technique to process what she's learned, illustrating the data where it lives. 

She offers original work as well as fine art canvas and paper prints, and clothing of her work. 


Portland Open Studios Fall 2019

The Portland Open Studios is a two weekend, city wide art experience where the public is invited to engage with artists in their studios where they create their work. Visit my studio and 114 other artists all around Portland during the second and third weekend of October. I will be showing my Numberism technique, pan pastels, possibly a glowing painting, and my partner will show you how he stretches our canvas prints. Hope to see you there!

October 12, 13, 19th &20th!

Take a moment and look closer.

Every mark in my drawings is a number or an equation drawn by hand. These pieces take me roughly 100 hours to draw and upwards of a year to research. They are best viewed with a magnifying glass, curiosity, and a little time. The numbers and equations that you see composing my work tell a story of the subject by way of scientific data and formulas. From measuring the health of a human heart to calculating the probability of life in the universe, my pieces beg the viewer to look closer and ask meaningful questions about the work and the sciences that inspire them. I myself struggle with math and use this work to show others that there is more than one path to a rewarding relationship with science. I include descriptions with all my work detailing the data I have used so that my collectors can share in my love of science and continue their own curious and creative journey.


Sienna has been based out of Portland, Oregon since 2009 and maintains a thriving business out of her working art studio in St John’s.

You can find her at the Portland Saturday Market every Saturday and Sunday from March to December 24th in space 803.

Commission Request Form

When I have completed my current commissions I will review new submissions and choose those which most inspire or connect with me. If you would like to commission me to create something special for you, fill out the form below. You will receive a response email only if I have selected your request for my next commission. Feel free to continue to submit additional requests. I am expecting to limit myself to 3 commissions a year.

Pricing: Cost is based on time to complete the drawing, researching the subject, and the cost of the materials. I will email you with a cost estimate when we discuss your commission. Payments are made in installments, with a down payment made before I begin my preparation. Final payment will be requested after the illustration is complete. We can ship the finished illustration anywhere on the planet, or you can schedule a pick up. Local buyers can also request delivery.

*Note. Exclusive commissions are charged at twice the usual rate. An exclusive commission is a drawing I am not allowed to reproduce.

Thank you for your interest in my work and I look forward to reading about all your lovely ideas!
