SEVA 2026 Triangle Tessellation

About the Exhibition

To better understand sustainability or environmental topics, visualizations are often helpful — such as satellite imaging of the polar ice caps, graphs of CO2 levels on Mauna Loa, the Recycle your attitude plastic water bottle sculpture, and the Crochet Coral Reefs collaboration. It is through art, photography, data visualizations, and other visual representations that people attempt to interpret and communicate the world and its largest challenges.

During MathFest 2025, the SIGMAA-EM displayed visual artworks that communicated sustainability or environmental issues in a community or our world. This year, we continue the tradition with a new tessellation shape.

The Diamond Shape

This year's SEVA entries will be two congruent isosceles right triangles, joined at their hypotenuses to form a square, rotated 45 degrees to create a diamond shape. Your final pair of triangles (square/diamond) will be printed with 7.5 inch sides.

Submissions should be oriented as a diamond (rotated square). The artwork should include the artist's name(s) and email address(es) in the diamond image/design.

Visual artworks created through collaborations are encouraged. Submissions must include sustainability or environmental content.

How to Participate

There are two wonderful ways to share your SEVA artwork — and we'd love for you to join in either way:

1. Join the exhibit in person at MathFest 2026. Bring or create your diamond-shaped SEVA artwork at the MathFest 2026 exhibition area, and we'll add it to the Triangle Tessellation on display in the Boston Conference Exhibit Hall. In-person submissions are the ones featured in this year's physical exhibit — we hope to see you there!
2. Share your art online through the end of 2026. Can't make it to Boston? No problem — your art is still very welcome! Submit your diamond artwork any time through December 31, 2026 using the Google Form, and we'll proudly feature it on our online SEVA 2026 gallery page. Please note that online submissions join our online gallery rather than the physical MathFest exhibit.

You can share up to three diamond-shaped SEVA artworks. Please complete a separate Google Form for each submission.

You will need a Gmail account to use the Google Form. If you do not have one, please email Bronna Butler at Butlerba3@gmail.com for assistance with your submission.

Creating Your Artwork

You can create your diamond artwork in several ways:

• Hand-draw your diamond-shaped artwork, photograph it digitally, and upload the photo file
• Create a digital design using Microsoft PowerPoint, Word, Outlook, or Excel (cropping instructions)
• Use Adobe Illustrator, Photoshop, or software apps like Canva

By submitting your online application, you agree to allow your artwork to be shown with, and to appear in photographs of, the 2026 SEVA Triangle Tessellation. The Exhibition will be available on the SIGMAA-EM website.
