Okay here, I've modded the lockscreen lock, so it just looks better ;)
I've created flashable zips, which edit kg_security_lock_normal.png and kg_security_lock_pressed.png in /system/framework/framework-res.apk/res/drawable-xhdpi/
For now this only works on Xhdpi devices (nexus 4, galaxy nexus, galaxy s III...) and ONLY WITH SECURITY LOCK on Android 4.2+!
This will work on any Rom with 4.2 or higher as it only morphs framework-res.apk

Current colors are:
Google Play music Orange
]50% Holo White
Tell me what colors/shapes you'd like and I'll make them!
as always, I take no responsibility to bricked|burning|killing devices :P (but I will try to help as much as I can)
Happy flashing :good:
