JUBILEE — Youri Messen-Jaschin
Celebrating the 85th birthday of Swiss Op Art pioneer Youri Messen-Jaschin, Jubilee is an exhibition dedicated to a major figure whose work has explored the dynamics of perception for over six decades.

Rooted in perceptual instability, rhythmic modulation, and optical vibration, his practice engages the viewer in an active visual experience where geometry and color continuously shift and evolve.

Opening: Thursday, April 23, 2026 — 6 PM to 9 PM
Exhibition dates: 23.04.26 — 14.06.26
Location: Laurent Marthaler Contemporary, Av. des Alpes 80b, 1820 Montreux, Switzerland

Op Art stimulates neuronal activity: neurons interpret geometric structure, frequency, and vibration.
Depending on viewing distance and angle, they mentally reconstruct an illusory three-dimensional depth where geometric forms seem to appear and disappear, while certain colors transform into others.
From a flat surface, perception creates visual depth and motion.

find optical illusions, there are several.

• 16.02.2025 Purchase Award Winners : Youri Messen-Jaschin for HOUYHNHNM – Work will be added to the CollexArt Collection.– Boston USA.
  Collexart says : The screen printing is gorgeous and intriguing! It is impossible to look at it all at once. We get lost looking at various effects in the different quadrants. It’s a beautiful piece, and we’re excited to have another one of your works in our collection.

Op Art, or optical art, features works that often feature repetitive geometric patterns, striking contrasts, and illusory movements that create an immersive visual experience that never ceases to captivate.

But that’s not all: Op Art goes beyond aesthetics to connect with science, particularly neuroscience. Observing these works activates our neurons in unique ways, revealing fascinating mechanisms related to visual perception. Why do some illusions appear to move when they are static? How does the brain interpret these plays of light and shape? We delve into these intriguing questions to better understand the subtle dialogue between the eye and the brain.

Whether you are an art enthusiast, a neuroscience aficionado, or simply looking for a sense of wonder, this exploration of art in motion will offer you a total immersion in the transformative power of Op Art.
