I'm trying to emulate the functionality of a Nimslo or Nishika camera to create animations like these:

The StereoPi itself has two dedicated camera ports, and you can connect only one camera per port.
One solution for your Nimslo-like shot would be to use two StereoPi boards working together.
A simple and dirty way would be to use an external button as described in this thread and connect the button to the two StereoPi boards (the way exposed there allows it without damage), but the jitter might be too large depending on the speed of the elements in your scene to freeze the two pairs at the same moment (not tried, but there are lots of jumps prone to introduce jitter, although unloaded systems might serve the request without much delay). Water falling like in your example require high speed synchronisation for example.
The more elegant way I have in mind would be hard to summarize in a forum post.
