Building on the previous research task, make your own optical device and create a short animation to work with it.
If you are less technically minded, an easy starting point would be a flipbook, and the easiest of the devices to make would be a thaumatrope or zoetrope. You can find plenty of tutorials online on how to make them.
If you are more technically minded, you may want to try experimenting with a Raspberry Pi or other software related optical device.
Add photographs of your working processes to your learning log. You could use the building of your optical device as an opportunity to create your own stopframe animation by sequencing your documentation or creating a short animatic showing the making process as well as the resulting animation.
