This illusion bowl is approximately 18 inches tall, 17 inches wide. It contains at least 10550 pieces. It is made out of walnut, maple, bloodwood, yellowheart and bubinga. This is the bowl that was made after I made a mistake, had to cut out 13 layers which ended up making the bowl I showed earlier this month called Oops. My son and I had approximatel 140 hours of work into this bowl.
