fun with redstone: carpets as pressure plates

[Thorin]

This tutorial shows how you create a redstone circuit that allows you to use carpets as if they were pressure plates (the trick here is to use redstone ore to cause a block update when you walk over it, then use the carpet over the redstone nore to hide the redstone ore).  This means truly hidden pressure plates.

There are also some great other ideas, like using two hoppers with one item between them as a T flip-flop (the item simply gets transferred from one to the other).

Note to self: Never touch anything ever again

It's a really cool idea, though, isn't it?  I wonder if there are any other blocks that cause a block update when you walk over them.

One of the more clever things I heard map builders do is create mob spawners for villagers in hidden rooms so that when a player is in range of an area an effect can be triggered by a villager spawning and tripping a red stone circuit connected to a pressure plate

I thought the cow proximity sensor was interesting...
