The Heart Equation for Google

When you put any Math equation in Google, it will try to plot of a graph of that equation just like your scientific calculation. And one such equation, listed below, renders a heart curve that you can pass on to your Valentine.
To give it a try, just copy-paste the following query in Google.

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
