Sulfur Cube function

Allow us to display items in a sulfur cube, it would be cool if maybe right clicking a cube with an item or item frame allowed us to display an item inside the cube, or maybe even make it so we can change the color of the cube with dyes. Or even make ot so feeding it red stone made give out a signal, but it’s a movable signal in a very unique way. Just a few ideas for the new sulfur cube
