Default Android L Style Notification Bar

Hi..

Was just wondering if any experienced developer out there is working on or has a link to the new style of the Android L Notification Center. Pretty much looking for a working MOD that would work with the Current Android version we have. Something that doesn't interrupt my phone calls and scrolls down from the top exactly like Android L. If anyone has access to any of this or would like to work on this please keep me in the loop and appreciate all the hard work in advance!
