MotionArtist is a very cool piece of software that allows you to layout comics in traditional panel form with word bubbles, and also add motion, sound, and even a 3D parallax effect to scenes. The animation tools are designed to be quite easy to use, and it's focused primarily on adding motion. Through our deal, you can get it for $9, a lot less than the $60 retail price.
