Drawing with Math

I found this app (and these groups of apps, it seems) out of pure curiosity and boredom on the App Store. From what I understand, the drawings in the “System Images” are made from mathematical equations. I think adding the formula into the caption of the image or creating a side annotation on each drawing describing the calculations done to form these drawings would make it more intriguing and understandable. Also, in the drawing modes, I think that once a transformation was done, or a line was drawn, that a formula or calculation likewise to the System Images drawings could pop up, creating a more detailed learning experience for the user.
