Kudos to the math geniuses who came up with an equation that you can plug into Google search to create a little Valentine's Day surprise.
The magic math that makes the heart graph you see above is this:
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
Go ahead, give it a try. Just paste it into the search box and see what happens.
The “cos(300x)” part of the formula was also written to make the line go quickly up and down as it traces out the interior of the heart. This creates the colored-in effect. Meanwhile, if you change the “300″ number in the equation to “500,” the color fills up the heart. That part of the formula is related to frequency.
You can also go to Wolfram MathWorld and try your hand at making a heart using one of the mathematical curves that produce these universal images for love. Or try this "Mathematische Basteleien" page, which gives you step-by-step equations to tailor your heart to your heart's desire. You don't need a fancy diamond necklace or a box of chocolates to make someone's day.

Cut and pasted it, but it does not work. There must be some small difference in IE9. A lot of people, on various browsers, report that it does not work for them, so don't be surprised.

Works for me, Firefox with Vista.
Just use a crayon ....
Did not work in Google search. Did work in Bing on the second layer of search.
Your search - 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 - did not match any documents.
Well, so much for that genius idea!
