Not sure if this has been brought up but I aren't it on everythingapplepro.net when I was jailbreaking my ip4.

This tweak has been around for a while but it never worked on 4x until now. With many customizable settings its just very cool. To get it you need to open Cydia go to Manage, Source, Edit, Add and and this source: Cydia.heaveniphone.com . Then search for androidlock xt for 4x and install. Now go to settings, set up a new pattern, tweak the appearance and enjoy! Yes this does work for iPad also!
The tweak itself is limited to 9 lines but can be changed to the folowing themes: AndroidLock HQ (for retina displays), Blades, Hauemgod, Pac Man, & Squares
