Dinnerbone has tweeted some sweet looking additions to Minecraft. Apparently he’s added a much requested feature to Minecraft: Frames to house and showcase items (a mod implementing shelves had been popular at one point). Here’s a screenshot showing frames over chests suggesting their contents, a screenshot showing maps, clocks, compasses, etc are displayable, and a more recently updated screenshot showing blocks and showing that he has added backgrounds to them to make them more easily visible. He’s since tweeted that all in-game items can be placed in them.
We’ll likely see this in some upcoming snapshots and in version 1.4
