Spirit Frame
The frame that tells you it’s level.
The spirit frame was inspired by that feeling you get when hanging a frame, Is it level? hmm (step back) I don't think it is, and you try again and again until you feel satisfied or you reach into your tool kit and pick up a spirit level. At this point my designing mind got curious, surely there are frames that have a function of letting you know when they are level, but to my surprise there was nothing on the market.
