This has been the background on my phone for years. Kerrigan has always been my phone's 'identity'. My text alert? The Overmind voice saying "Nuclear Launch Detected" from the original Starcraft. My incoming call ringtone? The Infested Terran sound file that claims "For the Overmind..." from the original Starcraft.
I should probably go find the newer sound files from Starcraft 2 since that game is actually... well real, instead of a pipe dream no one thought we would get.
