Nice bit of description from a book I'm reading. Created a very clear visual for me. (A group of good guys are creeping up on the baddies.)
Soft leaves crunched beneath their feet, and the light of the moon split into bullet-beams that shot between the swaying limbs.
I've never thought of bullet-beams, but it's definitely visual..
I would have probably gone for mini-searchlights or probing fingers. Not criticising here, I'm pretty sure my writing instincts would have gone with which instead of that because the beams are multiple.
Maybe just the difference between English English and American English.
