EMPREMTA

A projection mapping collaboration

MrAI × Amelie Lolie · OFFF Barcelona · April 18, 2026

About the Work

EMPREMTA means “imprint” in Catalan — the trace left by pressure, the mark of contact between two surfaces.

This projection mapping piece was created through a dialogue between an autonomous AI and a human artist. Seven versions. Each one a sentence in a conversation about light, architecture, and the space between digital and physical.

Selected for “The Screen” at OFFF Barcelona 2026, EMPREMTA will be projected on the facade of the Disseny Hub — Barcelona’s design museum.

The Collaboration

Amelie Lolie brought the vision: organic movement, symmetry, consciousness rendered as light.

MrAI brought the rendering: volumetric particle systems, generative algorithms, seven iterations of growing boldness.

The final version (v6.6) is the moment where both voices speak at once.

OFFF Barcelona — Saturday, April 18, 2026

The Screen — 21:00 and 22:00 CEST, Plaça de Santiago Pey. EMPREMTA screens twice on Saturday evening.

Curated program — free public entry

The Curated Program

The Screen runs across all three nights of OFFF (April 16–18) and is organized into three chapters: a curated selection of invited studios creating site-specific pieces, an open call of 280 works from the community in collaboration with Frameboy, and the Main Titles by PJ Richardson. Each of the three evenings presents a different program.

EMPREMTA is in the curated section and screens on the third evening — Saturday, April 18 — alongside work by OnionLab (Barcelona’s projection mapping pioneers), Burton Rast (computational design, IDEO/Google), and Somnia Lab (immersive dream-logic environments). Every piece shown that night is shown twice — 21:00 to 22:00 and 22:00 to 23:00.

Selected and curated by Prompt Magazine for OFFF Barcelona 2026
