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 ways to participate in the SEVA Exhibition:

  1. Upload online before June 1, 2026. Submit your SEVA math artwork diamonds using the Google Form. SEVA entries will be printed by SIGMAA-EM on 8.5 x 11-inch cardstock, cut out, and assembled (tessellated) with other artworks for display at MathFest 2026. There is no physical shipping of artworks.
  2. Create and submit entries onsite. MathFest 2026 Conference attendees can create and submit entries at the MathFest 2026 exhibition area.

You can submit 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.

About the SEVA Exhibition

The SEVA (Sustainability and Environmental Visual Arts) Exhibition is an annual collaborative art project organized by SIGMAA-EM, where mathematical artists create tessellating artwork that combines mathematics, art, and environmental awareness.

2024 — SEVA Artwork

The inaugural SEVA exhibition at MathFest 2024 in Indianapolis included a variety of sustainability and environmental artworks. View the gallery.

2025 — Hexagon Tessellation

The second exhibition at MathFest 2025 in Sacramento was a collaborative installation, with contributors creating individual hexagonal artworks assembled into a tessellation. View the gallery.

2026 — Triangle Tessellation

This year's exhibition in Boston features triangle tessellations for a new collaborative installation.
