A night version could be very doable, and would probably work best with a strobe light. I'm thinking a combination of glow in the dark streamers + strobe light would work best, or maybe just highly-reflective streamers so they "spread" the strobe light better.
I'll try to get a video of it being used a real situation soon, and by then I may have a night version prototype ready to be filmed also.
Thanks for the quick replies and feedback!
