Light will shine through paintings, but paintings have to be placed over solid blocks (which signs count as!), so you could make a wall like so: ####### ####### The hole in the middle would actually be 2 deep; you'd place a torch in the back, then a sign in front, then put a painting over the hole/sign; the torch would shine through the sign and painting, and light up the room (although the light would be somewhat diminished because the torch is recessed by 2 blocks).

One of the newest features, carpet , makes it extremely EASY to add lighting to your house without the need for fancy tricks.
Carpet allows light to show through, so easily placing Jack O Lantern s or Glowstone underneath carpets in your home allows for easier lighting, without all the hassle.

You could try these two methods of my own: Raise the floor with stone slabs, and put glowstone around the bottom.
Note:
In newer versions of Minecraft, this no longer works.
Since 1.4.2, half slabs block light from passing through them.
So although you can see the lit glowstone (and smooth lighthing may cause the surrounding area to light up a bit), there isn't any "real" lighting going on, so the rest of the room will still remain dark, allowing for things such as mob spawning.
Hide glowstone in a location
you can't see it, and let the light shine through glass.
(This works well at the top and bottom of your room; my example shines through both the top, and bottom of the wooden wall, I just used water instead of glass on the bottom.)
Note:
This is the piehole texture pack; the yellow stuff is glowstone.

I like to build lights into the wall thus:
### g # #l####### Where # is stone (or whatever your walls are made out of), g is glass, and l is lightstone, or a torch.

You can dig a 2 deep trench in the floor, then place a glowstone block on the bottom.
Once you place it, place a piston (either sticky or regular works) on top, and it'll give off the same amount of light as if the glowstone was above ground.
You can place jack-o-lanterns in the ground as well.
You could also place pressure plates (wooden or stone) over a jack-o-lantern that is in the ground.
It doesn't have the most appealing look but it is hidden and gives off a lot of light.
Hope I helped!

I just make a bush, but, instead of dirt for the bottom, I use glowstone or jack-o-lanterns because light can glow through leaves.

Lightstone is generally your best bet for things like this, because it can be worked into the design and shape of the room.
Obviously, people will know this is the source of light, but it doesn't stand out as starkly as torches or lava would.

Another way of doing this, besides the other answers: Redstone Lamp (powered by redstone, switches, or buttons)

Jack-o-Lanterns will provide light from underneath pistons, so you could put them beneath some for a mysterious light source.

For light that are concealed when turned off, use a piston system to pull out a glowstone and replace it with another, more inconspicuous block.

I would like to have a large underground room without it being either very dark or have light sources in the open (lava columns, torches). I use to build columns using stairs since they allowed light to pass through them, but this bug no longer seems to work.
How can you hide light sources while they still give light?

Use carpet to add lighting or raise the floor with stone slabs and put glowstone around the bottom.  Using glowstones and jack-o-lanterns and concealing them with carpets or underneath the floor is the best solution. Also, Redstone Lamp can also be used.
The most favourable solution seems to be the use of glowstones and jack-o-lanterns. Redstone Lamp is a viable solution.
