The ICS lockscreen implemented in CM9 is very similar to the rings lock screen implemented in CM7. Not sure what gummy looks like. Rings on cm7 had a lock, and silent "ring" you could drag to unlock, or silence your phone from the lock screen. It also had a confugiruable app starter ring so you could open apps from your lock screen. Useful for camera and stuff.
The lock screen in CM9 has all of this functinality, in a very similar layout, but it's one ring that you drag to your desired action, instead of many rings that you drag to open. You can add in launchers on the lockscreen section of system settings.
Maybe you've already seen all this, and dont like the new lock screen, and thats why you posted.
