Learning about the science behind optical illusions has been one of my favorite parts of this job. More and more, scientists are figuring out WHY optical illusions work on us, utilizing combinations of color, shadow, perspective, and how we process information to create impossible images, illusions of movement, and visual wonders to challenge how we interpret the world.

And I love seeing how people have responded by pushing the boundaries of what we can do with optical illusions. Earlier this year, I wrote about the glitch quilt, a fascinating and eye-wobbling work of brain-melting color play and meticulous execution.

In a world increasingly reliant on computer assistance and push-button AI-fueled shortcuts, there’s something both comforting and immensely charming about glitch quilts being handmade.

So it should come as no surprise to you, fellow puzzler, that I was overjoyed to discover another example of handmade optical illusion crafting… this time, made of wood.

This is the end grain optical illusion cutting board. It appears to bend and swirl and warp as you stare at it, despite being made of straight lines and alternating colors.

Although I discovered it through Obsessed Woodworking, this particular piece is the handiwork of Ryan Hawkins, who has a woodworking YouTube channel where he detailed the elaborate step-by-step process involved in creating this sturdy perspective-twisting delight:

Ryan, to his credit, pointed to another woodworking content creator who supplied the design plans for the cutting board: mtmwood.

mtmwood has numerous examples of handcrafted visual tricky, employing tessellations and tricks of perspective to fool the eye into following intricately laid patterns, and my favorite is easily one that they call the butterfly board:

Employing a similar technique to the optical illusion cutting board, but managing to shape four twisting patterns, is truly impressive and a testament to the hard work, skill, and technique required to bring these stunning pieces to life.

And, as you might expect, this sent me down a YouTube rabbit hole looking for other wooden optical illusions, and there are plenty to choose from.

This is a nicely executed attempt at showing dimension and depth to get us started.

Whereas this one walks us through all the stages of preparing to take a familiar optical illusion from a drawing to a three-dimension form:

I confess, I watched this next one three times in a row, trying to spot the seams:

I could go on and on, but honestly, instead of closing out on the illusions, I’d like to end this celebration of creativity and artisanship with a simple photo showing the preparation and painstaking work it takes to bring these pieces to life.

This is the optical illusion cutting board in its embryonic stage, a lineup of different pieces and thicknesses of wood. All marked and cut with precision, waiting for the next step in assembly. I stare at this picture, and consider every mark, every cut, every spin of the table saw’s blade as the creator runs piece after piece after piece through those whirling metal teeth, each of them perfect and crisp.

It’s a remarkable thing to ponder, and a joy to watch in both progress and in final realization. I’m glad I could share that with you today.

Happy puzzling, everyone!
