I'm not saying we need one like it would be the most useful thing in exsistance but if i think it would be cool if we could have hangable clocks, you make a clock the normal way with the 4 gold and the redstone but if you right click a wall it would be placed kinda like a painting but the icon would always be moving like a normal clock, it would be useful incase you need a clock and you have a few around, and when you punch the clock it turns back into the normal clock item for mobile use.
