Right after I finished my 3rd year of med school, I decided to write a suite that basically just took old designs, and rotated/mirrored/stretched them to make totally new and unrelated-looking designs. This is a very simple and fast pear design with a crown derived from my Tessellation suite, and it's pretty easy too! Works in materials from petalite to CZ (RI = 1.50 - 2.16) with no changes.
