Great job.
The two trampolines are very elegant, and hard to tune right.
My cantilever was almost as good as your final "dark" launcher (just $4 in it, I think).
Shame there wasn't more competition for you - that was an easy win in the end!
And I'm wondering, was the -100 score a deliberate mislead? (1672 vs 1772?)
Erring on the side of safety, at least!
