It's seems nice to me, maybe could be used when people get bored, that would make it fun.
But I think it would be better if that, when say something like Ojafest, goes on then we could use that as a spectacle(like fireworks, which is what you said).
But it would be an interesting game too, you could even make it so that you could make it a kind of hide-and-seek game where when you find somebody you can hit them with the arrow to let them know they're it...who knows.
