## Introduction: Is This Possible Impossible?

When I was a kid, I loved putting together puzzles. I decided to try and make a puzzle that is difficult, and by difficult, I may mean impossible. After many hours of trying to assemble this puzzle, I am still not done!

A friend of mine had made a puzzle out of clear acrylic that had no design and was just clear pieces that needed to be assembled together. At first I thought it may be a difficult puzzle and then I had an idea. I started by designing a puzzle with a design on one side of clear acrylic. After looking at the design, I thought it would be too easy to assemble. I wanted to make a puzzle that was difficult and possibly even impossible. Therefore, I decided to engrave the same design on the opposite side and rotate it 90 degrees to make it more difficult. This design has been the most difficult puzzle that I have ever tried to assemble and I challenge you to try and complete it!

## Step 1: Designing the Puzzle

For this puzzle, I decided to take one of my more complicated designs and turn it into a puzzle. I used a puzzle generator to create the puzzle pieces in combination with some manual editing to get the circular shape. I used vector engraving on this design for two reasons.

1. I wanted it to be as intricate as possible. Creating a vector line engraving makes it harder to see the design than a normal raster fill engraving would have.

2. Speed. Vector engraving the design is much faster than raster engraving and helps me make the puzzle in a fraction of the time.

## Step 2: Engrave the Design Onto the Acrylic

For this project, I used 1/8" clear cast acrylic. I had seen a lot of clear acrylic puzzles just cut into pieces, but adding an engraving to a clear puzzle, on both sides, makes it that much harder.

Once I engraved the design on one side, I flipped the acrylic over and turned the puzzle 90 degrees. To make this as complicated as possible, I thought that offsetting the designs from each other would make it more difficult to see where the design is supposed to go and where pieces line up.
