1. Create a short video sequence that loops well (that my preference)
2. Convert the video to numbered sequential images (I used MPEG Streamclip)
3. Drop the images into the Dropbox App
4. Assign each student an image from the sequence
5. Import the image into a layer in Brushes app
6. Create a drawing with a uniform protocol defining colors, line size, and strategy) in a layer over image
7. Turn back the finished drawing after deleting the image layer via email with image number as the subject line
8. Collect all images and convert into a video in iMovie or an animated gif using this tool
9. Then tweak your final product to make it eligible for the international Collaborative Student Animation project, Rotoball 2012
