The ever ace Seif Lotfy tweeted the following mock-up a wee while ago and, being both a self-confessed Docky Diehard AND a total Sezen head, my jaw was literally wedged open as an emphatic ”YES” careered its way out when my eyes fell upon it.
Created by chawsum over on DeviantArt, the design beautifully encapsulates the aesthetic of Elementary, the power of Docky and the sheer awesomeness of Sezen in one utterly awesome idea. 
Could this happen? Given the massive talents that lie over in Docky’s direction I wouldn’t hedge a bet against. If you do anything this week make it keeping your fingers crossed that this is borne into reality.
