Is it possible to make an active noise canceling system in the living room?

Question

Do it yourself

Many headphones have active noise cancellation built in. Is it possible to implement its analogue for the living room using speakers, microphones and a computer with special software? Theoretically (with very good equipment and a bunch of microphones) and practically (budget option). What will the sound experience be like in a room with a perfect noise canceling system?
