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.

Numbers are beautiful. If they aren't beautiful, nothing is.” Paul Erdõs

Every mark in my work is a number or an equation drawn by hand.

I am not a mathematician, I am not a scientist, and I have no real artistic training. If you gave me a multiple choice question about education, I would tick off the little box next to “some college”, and even then I would just barely qualify. I've come to my love of science organically, and I've never known any other way to be than an artist. I'm self taught in most everything I do, so I've really made a career of being curious and persistent.

My pieces take me an average of 200 hours to draw and upwards of a year to research. My media is pen, pencil or color pencil on paper or etchings on scratchboard, metal or glass. I use the smallest nibs I can find and often work under a magnifying glass.

Without a math or science background, studying things like the body and brain can be daunting. I have found that illustrating what I've learned with data that define the subjects function, connects me to it in a meaningful way and provides me with a lasting memory of the material. As an artist and science enthusiast, it is impossible to learn and not be inspired. This work is my way of sharing that awe and love with you as it continues to motivate me to study and learn about subjects that may seem out of reach, given my background.


Sienna has been based out of Portland, Oregon since 2009 and maintains a thriving business out of her home studio and gallery.

You can find her at the Portland Saturday Market every Saturday and Sunday from March toDecember 24th. In 2017 you can find her in spot 904.

Commissioned Work

*Note- There is currently a wait list for Numberism Commissions. To get on this list, email her though the contact page.

If you are interested in a custom original Numberism drawing or etching, send an email through the "Contact Us" page. Prepare several months ahead of the time you would like to receive your original Numberism drawing. These are known to take anywhere from a few months to a year to complete. Sienna works one on one with custom buyers to find the numbers and data best suited to illustrate your idea. Pricing is based on detail and required research time. Payment is received in installments. 

Price Breakdown: 

$800 - $2,000 a square foot, based on detail, payable in installments. 

Square Foot = W x H / 144

Square foot x Detail price = full price of piece


16 x 20 \ 144 = 2.2222

2.2222 x $1500 = $3,333..

The above example is for one size. Sienna has created custom pieces as small as 5" x 7" and as large as 32" x 40". You can pay for this in two or more payments. Larger pieces that will take more time can have longer payment plans with smaller increment amounts. Once the artwork is fully paid for, we can deliver or ship it to you, or you can schedule a time to pick it up in Portland, Oregon. 

Original work comes with a certificate of authenticity, with a full description of the numbers used, as well as a magnifying glass. 

Below is a gallery of Custom Numberism drawings Sienna has created in the past.

Update on Charity Donations and discounts through this website:

Instead of saving a few bucks here and there, let's make some positive change together! 

Starting in January, 2017 this website will no longer offer discounts via coupon codes or sales. Instead 5% of the listing price of every item sold on this site will go to your choice of one of four charities, which you can select in the check out.  These donations will be deposited quarterly. Check back here by the end of April, August, and December to see how much we have donated together to each charity respectively. I appreciate your support and understanding as I remove discounts from our website and instead direct some of our sales to making positive change in our community and abroad. 

During popular sales like "Cyber Monday" or "Small Business Saturday"  10% of the listed price will go to the charities rather than 5%.

The Charities for 2017:

  • ACLU
  • Planned Parenthood
  • Oregon Museum of Science and Industry
  • Oregon Humane Society

If you would like to receive coupon codes for discounts on my work, you can become a patron on to get 5% and 10% off coupon codes. This is the only way to get discounts online. Thank you. 

The difference we've made so far: 



*Note: This donation option was made available on this site on January 29th, 2017. For sales made before this date in 2017, we have directed the donations to the ACLU.
**Sales from our Etsy site (  will also have this option. We are arranging this donation option as we speak. Information about donations aquired from both sites will be updated here quarterly.
