Inverse Graphing Calculator

Inverse Graphing Calculator: "The Inverse Graphing Calculator (version beta-1) is like a backwards graphing calculator. Normally, you enter an equation into your calculator and then get a graph of the curve. The way the IGC works is, you type something you'd like as your curve, like 'Hello World' or 'I love you'. The IGC produces an *equation* which has this phrase as its graph!"
