A friend posted a formula on Facebook together with a simple instruction to copy and paste it on Google. Hitting the enter button will instantly give the result shown in the screencap below.
(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

This probably proves that math can be fun and definitely can be used to express feelings or emotions. Happy Valentine's Day!
