One of the things I absolutely love to do is using materials to control my lights in ways that are not “standard”.
You can of course use a metal sheet with holes to create some nice patterns, however if you make the holes “small” enough you can use it to place the model behind it and the reflection of the material will actually bounce back to the model.

In this case I used one strobe with a red gel and one standard strobe just for fill in.
