Just by looking at the wallpaper from the image above, I wanted to download this CM7 lock theme. Sad thing is, the wallpaper does not come with the lock theme, and cried just a little because she is HOT. Okay well after I dried the tears rolling down my cheeks and flashed the zip file, I was pretty impressed. Lockscreen definitely has a nice MIUI look to it now.
With this theme, you of course have those options of using the sliding tab, bubbles, the lense, or the rotary. The bubbles looked pretty sweet with the ripples around the and the lense lock style matched the MIUI style completely. The revamped rotary I thought was the best looking style to go with this theme. Something about how the silver bar that goes across the screen is very eye-catching to me. I kept turning my screen off and on just to look at it again and again. So check this theme out for your CM7 lockscreen by clicking the link to the thread below. Make sure you backup just to be on the safe side, and flash away. There is also some custom icons you can add to it for those who want to get to certain apps from your lockscreen. Now I am determined to find out who that girl is in the image above.
