A lot of this work reminds me of a guest lecture by the photographer Andres Serrano that I saw in college. At one part he showed us some recent work of his from a series titled 'Ejaculate in Trajectory'. While I expect that like Serrano the artists have enjoyed making these I'm not sure what else there is to gain from them.
I see it as filling out the space of possibilities within computer graphics. E.g., CGI in movies might be more practical and technically difficult, but what else can we do? It's interesting to see the boundaries pushed at least.
I can't speak about photography art but in the case of coding art, I've learned a lot about linear algebra and algorithm design by making fun art projects.
