Lol, An Actual Easter Egg In Google Search

Had a friend post this in a Facebook post, and I'm not sure its really a easter egg in the internet sense, just so serious geekery, but it definitely is an Easter egg in the traditional sense.  Just enter this exact phrase in google (google shortens it on the displayed page, but re-entering the shortened part only brings up web page results):

1.2+(sqrt(1-(sqrt(x^2+y^2))^2) + 1 - x^2-y^2) * (sin (10000 * (x*3+y/5+7))+1/4) from -1.6 to 1.6

 

 So, did you enjoy?  Its even colored for that really Easter egg flare.  Keep having fun and happy Easter everyone.
