Works in Firefox, and I suspect Chrome. Didn't work in Opera or IE9

Just google

sqrt(x*x+y*y)+3*cos(sqrt(x*x+y*y))+5

well, edit some certain parts and you can create some different and unique graphs

eg/ all i did here was negate the x*x+y*y bracketed sums and came up with this :
https://www.google.com/search?q=sqrt%28x*x-y*y%29%2B3*cos%28sqrt%28x*x-y*y%29%29%2B5

here is another good one.

tanh(y(y^4+5x^4-10(x^2)(y^2))/(x^2+y^2)^4)

And this is a list of some more.
