I made this simple macOS application that displays random images, from a folder, rapidly at the refresh rate of your screen. It has an option to center faces using ML detection.
I originally built it as a tool to help with aphantasia but quickly realized it didn't help much. The main problem was that it's no different than just watching a movie, or playing a video game. However, when viewing hundreds of faces in a few seconds, you realize that your brain's visual processing center is selective, and you actually start to notice patterns across various images.
