[q] 4x4 or more; grid pattern unlock?? topic

I currently using purity rom and i love the 4x4 grid patten unlock feature. It goes up to a crazy 6x6 (if you didn't know)
I am a bit bored of this ROM as I have been using it since I got my phone( 3 months ago)

I looking for other ROMs with same feature.

Is there a way a can take this feature with me to other ROMS?
