I love what Google does to have fun; just look at their April Fools stuff from this year. But now they have what may be the best Easter Egg ever! Just Google the Following and the egg you see above will be revealed.
Google this(or just click it):
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
I just hope someone spent their 20 percent time on this. Hopefully they start spending some of it on Android, too. Happy Easter!
