Animation in Photoshop
Many students don't realize that they can animate in photoshop. It's not the same as animating in Flash or After Effects, but you can create a range of movie files (from animated gifs to quicktime movies), without learning an entirely new program.
Be sure to watch tutorials for the version of Photoshop you use. (The animation tools are slightly different in every version of Adobe CS...)
