Pixel-Logic is a pixel art tutorial by Micheal Azzi, which is being kickstarted now. It has already gone far beyond its $5,000 goal. this peaked my interest because pixel art is always something that has interested me and I have done some work with pixel art in the form of spriting for video games. I hope this tutorial turns out really good and i can not wait for it.
