An easter egg for the StarCraft fans.
Every now and again, the fine folks on Google's search team will take time out of their busy days to surprise us with a fun little easter egg. Some of our favorites have included 'Tilt,' which put all your search results off kilter, 'Do a barrel roll,' which rotated search results a full 360 degrees, and 'Binary,' which change the number of found results to read out in binary. However, this latest easter egg has just been bumped to number one on our list and will be pretty difficult to top.
Searching for 'Zerg Rush' will result in tons of Google little O's rushing down to destroy your search results little by little. Clicking on the O's will kill them and a little score box to the right monitors your APM and score.
