TOOLS: Krita

One aspect of motion design that seems to be having a resurgence lately is the use of traditional hand drawn frame-by-frame or "cel" animation (I know, it's all digital now but plenty of people still refer to it as cel animation). I personally really need to up my drawing game before I get too serious about hand drawn animation, but if you'd like to give it a shot, try downloading the FREE open source drawing/painting program, Krita. They have integrated animation features as of version 3.0, so check it out!

By the way, here's the link to the animation section of their documentation to help get you started.
