There are some mods for this, but I think Notch should add some more interactive locks to the game for decoration and use. Things such as furniture that you can sit in and window shutters that open and close over the window. and for decoration in towns signs that hang out over the street of the building (sorry not a good description but i hope you get what I mean). Also some more redstone feature like blocks that have internal wiring the crafting recipe being a square of blocks with redstone in he middle, like so:
= redstone
the end result being 8 blocks that look like the original but have redstone like attributes. This would allow for a light fixture (Another idea in which there is a light source of some sort that is as bright as a torch but can be turned on and off with redstone and can hang from the ceiling) that could be turned on and off without large hidden redstone contraptions behind walls.
Let me know what you think and what other ideas that are in the same category as well that you have
