I found these websites useful when looking for details about thaumatropes:
- Princeton Online: helpful science demonstrations (and more, I’m sure).
- Bright Bytes: examples of Vision Toys that demonstrate the concept of persistence of vision.
- Random Motion: one of the best definitions we could find, and some great experiments that even worked for me!
- Micro Magnet: examples of animated GIFs demonstrating thaumatropes with less risk of human error than the “offline” variety”.
