When you get bored and ordinary boolean logic gates just won't solve your problems, and when AND-gates, OR-gates and XNOR-gates just feel too digital, why not make your redstone contraptions feel a bit more analog?
With a Goldilocks-gate, of course.
It (ab)uses the fact that redstone signals only travel 15 blocks. The first signal was too weak:
The second signal was too strong:
But the last signal was just right:
You can use it to control multiple redstone contraptions with a single line of redstone dust. The only caveat is that if you try to send more than one signal at a time, the strongest will override the weaker ones.
If (when) you use it, please leave a comment. I'd love to hear what you thought/made of it. :)
