Yeah I found that
Wave Launcher and
CircleLauncher, but i think that is an actual launcher, not just a lock screen quick launch widget.
The CircleLauncher is very very close since is has that mac style animation.
I also found
UlitmateFavesPro which is a Carousel style launcher, but again, not a lockscreen widget.
Everything indicates that he is using Widget Locker so it is most likely some type of Widget Locker add-on that maybe not many people know of.
If he is using Widget Locker it would have to be a Widget Locker widget right? I don't know of any lockscreen widgets that work cross application, unless it were some type of FRAMEWORK mod that is installed directly to the ROM, but i doubt that, the status bar looks stock.
There is still an off chance it is
Launcher Pro Plus Unlocker, but I tried searching google images and youtube but didn't see anything like that.
I know that the person also has
TSF Shell Launcher according to his other posts, and TSF Shell does a lot of stuff like that, just watch the video...however nothing about lockscreens.
