That extra layer of poly sure made the Praxinoscope shine, good job Lenn !
Shame that the focus wouldn´t stabilize, but the movie gave a good idea nonetheless.
Perhaps the camera works better under different exterior lighting?
This is one of the few things an older smartphone would be good at, since they don´t change their focus distance once they are filming.
I use one here on occasion, to avoid my real camera focusing on closer objects, as one can hold the camera away from obstacles and focus, and then move it back inbetween anything, and it´ll keep the initial focusing distance.
