This one is my dad's brainchild. He came up with the design for it a couple of years ago, and we've built one at my grandma's every 4th/24th that we're there since. Here's a video:
Cool, huh. The whole thing is made with the contents of 24 crackle bombs (the little green round things about the size of a smoke bomb). It takes its name from the fact that the actual firework, once built, looks like a miniature take-out box from a Chinese restaurant. I'll post instructions on how to make one, along with some pictures of the actual firework, sometime in the future.
