mtPixy is a lightweight pixel editing program that I created from scratch. It is a small, no frills program which is designed to handle simple day to day tasks. I have put the most important facilities I want into a small customized program which means I can avoid the problems of larger programs such as slow operating speeds and overcomplicated user interfaces.
