After a life of loving the works of MC Escher I felt compelled to honor his work, taking it to the next level by vectorizing it. After coming across an amazing gift wrap book that exclusively featured sheets that are the works of MC Escher, I became obsessed with this piece of his work by staring at it hanging on my wall.
Using Inkscape I traced the lines of a fish and cut a few out with a laser cutter to see how they fit together. The result was about 10 fish that fit together, but not really tightly. The fish lived on my desk at work, allowing others to play with them. Seeing how much fun people could have while playing with a small puzzle that did not require a lot of puzzle solving inspired me. But then life took over and I got busy for 18-months and did not have time or access to a laser cutter to finish the project. So here and there I would occasionally tweak the design, trying to reduce tolerances and improving layers.
