They look like instruments of torture to replace water boarding techniques.
Sort of reminds me of that Jeremy Irons film and his twin brother who made some nasty tools.
Are the shapes hollow? did you spin some of the parts?
Are the materials brass and copper or just made to look like that?
Do you manage to sell many items.
How long do they take to make on average?
In some ways they look futuristic and in other ways they look turn of the century like you'd see with a mad professor.
EDIT:
The film was called Dead Ringers
