The Magic Piano

A piano can produce beautiful music if you know how to play it, but what if you could see the music as well as hear it? This idea presented a challenge for the guys at HTX Studio, and they spent three years making it happen. In this video, we get to see the many ideas that didn't work, which are all pretty cool anyway. With every failure, the challenge became more important, and that's why they persevered to the end. 

We also have to admire this guy's dedication to learning to play piano in those three years, in order to do the magic piano justice. The result is not only a fascinating musical instrument, but also beautiful music and an astonishingly high-quality DIY video. (via Metafilter)
