Google has a Valentine Day equation

Here's a trick to impress your Valentine. Just type in this maths equation in the Google search bar: "sqrt(cos(x))*cos(300x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01, sqrt(6-x^2), -sqrt(6-x^2) from -4.5 to 4.5" and wait for the magic to unfold.
A beautiful heart appears on your screen, sans paint or brush. The only catch is that it works in Google Chrome and does not support Internet Exlorer.
