Pacman-Arrow for LockScreen is a mod published last night in Cydia, and with its help you can stylize the slider for unlocking iDevices. If you look at the image above, you will notice that the original slider from iOS is modified to include the famous image of PacMan, and fans of the game will probably appreciate this small change. The mod is 100% compatible with Retina screens of iPhone/iPod Touches, it could also work on terminals without Retina, including iPads, but it has not been tested.
Pacman-Arrow can be installed for free from Cydia's ModMyi repo.
