Random Time! - Drawing Pokemon using mathematical formulas

I don't know why people do the weird things they do. I'm just happy they do them. Case in point, the Pikachu and Dedenne drawings you see above. These were both created using complex mathematical formulas. For example, here's what's needed to draw Pikachu.

I'm a horrible artist, so using the formula above might actually be a better way for me to get a decent-looking Pikachu!
