I enjoy creating symbiotograms, an ambigram that, when rotated 180 degrees reads as a different word from the original. Usually they are random words that are related, like synonyms or antonyms, or someone's first and last name or nickname. This is an example of a symbiotogram I made for a friend of mine. I designed it so when his first name was flipped 180 degrees it spells out his last name. When placed over each other it forms his full name when viewed 'regularly' and when flipped 180 degrees.
I enjoy designing and creating pumpkin carving patterns as well as carving them. It is a challenge to turn an image into completely black and white, forming a relationship between solid and void. This must be done while making sure everything is still attached with no floating pieces and the connections thick enough to hold up, all while still producing the desired image.
I have always loved the works of M.C. Escher. Some of my favorite pieces by him are Smaller and Smaller, and Metamorphosis II and III, as well as the normal tessellations. Creating a tessellation requires good spatial relationship skills and knowledge. Two more traditional type tessellations I created are dragon heads, based off of a tessellating triangle, and demon-like monsters, based off of offset rows of rectangles.
A complex tessellations created in the style of Smaller and Smaller, but with fish instead of lizards. The fish tessellate in such a way that the two adjacent shapes are half the size of the original, with each continuing set getting smaller and smaller. The fabrication of this is more complicated than a regular tessellation because the changes of one side do not only affect the corresponding opposite side. In this tessellation, the changes of one side affect another side, while both of these sides affect the third side.
