If you are sending your work from a country outside the EU, write on the envelope No commercial value. In case of customs duties, I will not accept the envelope.

No jury, no fee, no refund, no insults. All postcards and mailed artworks that include an explicit and clearly visible mathematical or geometrical element will be accepted. No return and no participation via email. Subtle references will not be accepted—mathematical or geometrical elements must be a dominant and evident part of the composition.

Exhibition runs until March 31, 2026

What We Are Looking For

We accept Mail Art submissions that explore the relationship between mathematics and artistic experimentation, including but not limited to:

• Geometric Abstraction – Postcards featuring mathematical symmetry, tessellations, and fractal-inspired designs.
• Algorithmic & Computational Art – Artworks created using mathematical functions, cellular automata, AI, or algorithm-generated patterns.
• Number Theory & Cryptographic Elements – Visual representations incorporating prime numbers, Fibonacci sequences, or encryption-based designs.
• Experimental and Hybrid Forms – Mixed-media or unconventional mathematical interpretations in Mail Art.

All accepted works will be featured online only at space.rochallyi.com, as part of The Wrong Biennale digital exhibition.
