Main Project: Optical Illusion Cutting Board

I am designing and creating a cutting board that incorporates an optical illusion pattern using different hardwoods. This idea originally stemmed from a wooden toilet seat my parents own, which features a lion graphic. My initial inspiration came from wanting to craft my own wooden toilet seat after my current one broke. However, after researching optical illusions on wood, I discovered cutting boards with intricate illusions, which shifted my focus. Given that I also need a new cutting board, I saw this as an opportunity to challenge myself creatively and technically.

My primary inspiration comes from optical illusion wood patterns, particularly those that create depth and movement effects. I found several cutting boards with intricate illusions, some appearing to bulge or warp, and others featuring geometric arrangements that trick the eye. The first two images in my reference gallery depict bulge and pinch illusions, which I find particularly compelling. Optical illusion designs have long been used in art and design to create a sense of movement or three-dimensionality on a flat surface. These illusions rely on contrast, shading, and geometric precision to manipulate perception. I will be referencing traditional woodworking techniques as well as modern digital design methods to create my illusion.

While many cutting boards use a simple striped or checkered pattern, my goal is to create a more complex optical illusion using rectangular pieces arranged in a grid. I plan to manipulate different wood sizes and color contrasts to enhance the illusion. This approach is adapted from the techniques used in optical illusion parquet flooring and inlay work. Optical illusions in woodworking often require careful planning and execution to ensure that the final design aligns correctly and maintains its effect from multiple viewing angles. The selection of woods with distinct color variation is crucial in achieving the desired contrast for the illusion to be effective.

I envision this cutting board as both functional and artistic. It should serve as a durable kitchen tool while also acting as a visually striking conversation piece. I aim for an aesthetic that distorts reality, using geometric precision to create an illusion of movement or depth on a flat surface. It must be food-safe, durable, and easy to clean while maintaining a strong artistic presence. I plan to integrate an ergonomic handle for hanging and a routed groove on the surface to collect liquids. The combination of form and function is essential in this design. While the illusion will be the focal point, the cutting board must remain practical, allowing for easy maintenance and usability in the kitchen.

While my primary focus is on optical illusions, I also considered two alternative aesthetics. The first is a wavy pattern style, which features wavy or high-contrast geometric patterns. While it might be challenging to achieve with wood, it could work for a future project such as a custom toilet seat. The second is a modern minimalist modern approach, using sleek, dark hardwood with a simple, elegant design. This would be easier to execute but less visually engaging than an illusion-based design. Ultimately, I chose the optical illusion aesthetic because it presents a greater creative and technical challenge. The visual engagement of the optical illusion cutting board adds an element of surprise and delight, making it a unique and artistic kitchen accessory.

I started by sketching different grid-based illusions, experimenting with how the arrangement of rectangular pieces could create a sense of depth. Some of my early designs incorporated simple checkerboard patterns, but as I explored more complex illusions, I realized that subtle variations in size and alignment could dramatically enhance the effect. I am using the CAD software SketchUp to refine my design before fabrication, ensuring precise measurements and a well-balanced composition. CAD allows me to visualize the final product, adjust dimensions, and test different wood combinations before cutting. The precision provided by digital modeling ensures that my cuts will align perfectly, maximizing the effectiveness of the illusion.

So far, I have researched different hardwoods suitable for this project, sketched out design options, started a rough CAD model, and identified where to source materials. Next, I will purchase hardwoods from Consolidated Hardwoods in Broomfield, then cut and glue pieces together to form the illusion. The selection of hardwoods is a crucial step, as I need to choose species that provide strong contrast while also being durable and food safe. Some potential wood choices include maple and walnut for a striking light-dark contrast or cherry and ash for a more subtle but still effective visual effect. After selecting and cutting the pieces with the table saw, I will glue them together carefully, ensuring that the pattern aligns correctly. I might also need to use a planar but am unaware of a woodshop that has one.

After gluing, I will trim the edges, route the perimeter and handle, sand the surface, and apply a food-safe finish. The routing process is particularly important for both functionality and aesthetics. A well-crafted handle will make the board easier to store and use, while a juice groove will enhance practicality. The sanding stage is essential in achieving a smooth, polished finish that enhances the illusion and makes the board comfortable to handle. The final finish must be food-safe, durable, and enhance the natural beauty of the wood. I plan to use a combination of mineral oil and beeswax to create a protective coating that will preserve the cutting board over time.

I am expanding my woodworking skills, particularly in precision cutting and joining techniques. Additionally, I will learn more about finishing methods to ensure food safety and durability. The precision required in creating the optical illusion pattern means that I need to refine my skills in working with the table saw, glue-ups, and sanding techniques. I will document my entire process through photos of each step, time-lapse videos where possible, and written reflections on challenges and solutions. 

I am excited to review and provide in-depth critiques of two peers’ Design Preview Reports using the Critical Response Process. My critiques will include statements of meaning to highlight strengths, neutral questions for clarification, and constructive feedback that encourages improvement without prescribing solutions. Providing detailed and thoughtful feedback will help me engage with other students’ work while also refining my own critical thinking and design analysis skills. From classmates’ work in this class I feel I have gained tremendous inspiration for creative work.

This project is an exciting challenge that allows me to blend function with artistic design. Through careful planning and execution, I aim to create a cutting board that is both practical and visually striking. My goal is to push my woodworking skills while exploring my aesthetic possibilities. The process of designing, building, and refining this project will not only help me develop technical skills but also deepen my understanding of the interplay between visual perception and physical materials. I look forward to seeing how the final product comes together and how effectively the illusion translates into the final piece.
