First things first, credit for ClearLock goes to user holdemdogg on mmi.
The transparent slider is from user Pronup on mmi.
I was going to post a link, but only have 1 post so far (NOOB!) Search mmi for 'transparent slider' (2nd search result), which will then have a link in the first post to Clearlock.
This lockscreen is great! The wallpaper changes throughout the course of the day to show the different phases of the day - sunrise, morning, afternoon, sunset, evening, night time. It's just awesome, and I love it so much I wanted to share.
Cheers!
