Heres another lockscreen i created few days back.. took a little longer to get to the Play Store.. probably because the word Nazi, sent up a red flag somewhere.. anyway here it is.
I created it using the Go Themes Factory site and Inkscape for the artwork.
Feed the Nazi to the piranha to open your lock screen. because "slide to unlock" is for wimps... You need to install Go Locker in order to use this. You can use the Go locker settings to add your own wallpaper or use the launcher's wallpaper
To unlock your phone.. touch and drag the floating nazi to one of the swirling schools of Piranha.
Get it here at the Android Play store.
