Math is Fun!

I enjoy using perspective in my work, but I sometimes fly by the seat of my pants when it comes to being really precise with the linear relationships. Last semester, I had two delightful engineering students who kept saying, "But what is that spatial relationship, really?" They ended up teaching me some math/geometry skills that are helping me straighten out some mistakes I have made in my paintings, as well as help my teaching skills. Here is the almost repaired version of a painting called "Tipping Point", about global warming. Below are photos of the painting before the repair began, and one of the windows with the grid double drawn in, showing how the ellipse is divided to properly recede in space. Who knew math could be so fun and useful?
