This is an amazing way of making Steemit more engaging and productive. Kudos to this wonderful idea of yours. Pixelcraft sounds more than just our usual game. I consider it to be a creative movement powered by the block chain. One of the essential things I love about it is it ability to blend creativity, art, and technology in one basket while gaining.

Your choice of using metadata to store each colored pixels shows a high level of transparency and the fact that each users contribution will be tied to their Steem accounts bring some elements of pride and direct ownership. Honestly, I am impressed by this. I am looking forward to be a part of this epoch making project. Count me in.
