How to summon up the formula for romance in Google

If your web browser is capable of drawing 3G objects then it is possible to summon up a lovely romantic heart from Google.

This isn’t really a heart. It’s a graph that looks like a heart. If you’re curious the formula to make this graph is this;

5+?(-sqrt(?1-?x^?2-?(y-?abs(?x))^?2))*?cos(?30*?(1-?x^?2-?(y-?abs(?x))^?2))

Look like hard work? You can just skip to the end with this search here.
