Adventure game puzzle idea

[wallwalker]

On the one hand, obtuse adventure game puzzles bug me. (I still remember that one time in King's Quest 6 - the only way that I passed one of the early puzzles was by saving and using every single inventory item I had, and it was the very last item on my list that worked. There was NO WAY you could know that the particular item would do what you needed it to do unless you tested it beforehand, which I'd learned a long time ago NEVER to do in an adventure game because you'd end up using up something you would need later. And then the game got rough.)
On the other hand, I understand the appeal. They can be fun to come up with and find out if anyone will actually solve them.

A while back, when I was actually considering programming one, I came up with a puzzle. It's probably been done before, but I don't know. I don't know if it'd be extremely obvious, extremely irritating or something in between.
