Perspective Optical Illusions: The art of circling the square

When bending the sides of a square structure forward, each edge forming a sine wave shape, the structure reveals a circle when viewed from the reverse angle. This illusion plays with perspective, specifically utilizing an effect known as “anamorphosis“.

Anamorphosis refers to a artistic technique that uses perspective to create distorted images that can only be viewed correctly from a specific angle.

Two Mind-Bending Aquariums

At first glance, they seem to be the same, but take a closer look… Can you spot what’s wrong?

I’ve always been fascinated by impossible figures, which psychologists call “undecidable figures”, meaning visual representations that challenge our perception and understanding of reality. Since the late 1980s, I’ve continued to explore this field and create new illusions, producing a series of drawings that play with the third dimension, manipulating perspectives and proportions to create original visual effects.

My work draws inspiration from two masters of optical art and impossible objects: Josef Albers and Oscar Reutersvärd. Their innovations and creations have always inspired and motivated me to continue my research in this field.

Triangles of Beauty

Introducing my latest creation, Triangles of Beauty—a minimalist mosaic that blends geometric precision with visual intrigue. This op art piece showcases a striking arrangement of triangular shapes in sepia tones, merging rich shades of brown and beige. The triangle, a timeless symbol, embodies the balance of masculine and feminine energies, forming a harmonious third element that transcends duality. It represents strength, unity, and the divine—a visual echo of the trinity, where individual components unite into something greater.

Step back and let the patterns unfold to reveal the depth within this thought-provoking piece.

Globes within Spirals? (Optical Art Tutorial)

Are you seeing spirals? Look again, they’re actually concentric circles! This unique variation of the “Fraser spiral” plays tricks on your eyes by blending a regular line pattern (representing the circle’s circumference) with misaligned elements (the spheres with varying brightness).

“Infinity”, A Kaleidoscope of Squares

With this work, I aim to push geometry to its limits, transcending the confines of color. My goal is to showcase the creative potential of simple concentric squares as a medium for experimentation and the discovery of new op art patterns. By delving into this exploration, I strive to unveil captivating illusions of color and mesmerizing motion.


Draw a large and a small square with thick lines and center them (Fig. A). Next, blend the inner and outer squares in six steps to create a set of concentric squares. Reproduce the set to form a larger square pattern, as shown in Fig. B.

“Enigma”, Paradoxical Volumes

In these minimalist op art works, I explore geometry as metaphor, using the hexagon as a building block for cubes and other regular solids. The forms appear stable and believable, yet they are impossible. Their contradiction isn’t obvious at first; it reveals itself only when the eye slows down and follows the structure closely. By merging incompatible viewpoints and softening the boundary between inside and outside, the drawings turn logic against itself. The more ordinary the form looks, the stronger the effect—these objects are meant less to trick the eye than to unsettle the mind and challenge our sense of space.

Enigma 1: Available as fine prints and t-shirts.

The two drawings displayed above and below combine paired tribars to form an impossible isometric cube, where form and illusion lock into a single structure.

Enigma 3: Available as fine prints and t-shirts.

Here, the “volume” turns itself inside out, quietly echoing the logic of a Klein bottle and unsettling the usual distinction between interior and exterior.

I am currently in the process of writing an informative book titled “Mastering Optical & Geometric Art: A Journey to Captivating Creations.” With a length of 136 pages, this book serves as an engaging guide to creating visually striking optical art and intricate 2D and 3D patterns.

Illusive Color Mixing

When your brain lies… There is NO yellow, nor red, nor green in the picture below! The only real colors are blue, cyan and magenta. Scientists and artists call these color induction effects “simultaneous color contrast” and “color assimilation”.

Concept taken from my book “Drawing Optical Illusions” (2010).
