Origami that Moves!

Here's a link to the Origami Fireworks tutorial.

In the tutorial, they fold several sheets of paper at once, but I think it works better if you fold them one at a time. Fireworks make take several tries to build, but it's worth it!

For you movie fans: above my left shoulder is Ray Harryhausen's Ymir (poor Ymir!) from 20 Million Miles to Earth, and Gort from The Day the Earth Stood Still ("Gort, Klaatu barada nikto!")
