This dancing bird was inspired by a doodle that I tend to draw in my notes (and in my friends’ notes too…). Working with variables was a bit of a struggle for me, especially if something went wrong in the position or rotation, because then I had to figure out which variable the problem occurred with, as opposed to just toggling numbers, but this was a fun exercise to do!
