Using photoshop to create mini animations for elearning

Animated Torches primary colors

Is anyone else using photoshop to create mini animations for their elearning courses? Recently I needed to show the primary colours (RGB) mixing together to create secondary colours and remembered that photoshop could create basic animations (animated GIF or video). So, together with the 'Difference' blending mode I could create this little simulation of three torch lights overlapping and mixing together.

Here are some more simple animations built for a 'Video Theory' course:
