It's done!

I finally got around to finishing the trebuchet. All it needed was a sling and some cleverly tied rope. I took it out tonight and gave it a test run. I just flung some rotten potatoes. It needs some tweaking to get to optimal range -- so eventually it's going to be flinging stuff really far! Hopefully coconuts!
Here's the video! (and some photos!)
