Looking at the page, it seems like there's nothing other than art installations in the Showcase. https://visualprogramming.net/#Showcase Is there something about the software the predisposes it being used only for art installations? Or just the community it attracts? It "looks" capable.

It seems weird that out of all the showcases, there's not anything like normal industry projects. No games, no movies, no television shows. Lots of museum displays, AI scultures, art walls.

Take Blender instead https://www.blender.org/features/ and its almost entirely "industry production pipeline" and "award winning shorts and films". Or Maya, which is pretty much nothing other than "used in Hogwarts, used in Avengers, used in Dune." Notably, not very many art walls or digi-scultures.

Usually its a chicken and egg thing, like nobody uses it, because nobody famous has used it yet, except vvvv looks like it has plenty of users.
