Living room stalking, or stalking in a house, is just a practice in going very very slow. I have a very, very squeaky floor in one room. No matter what I do I can't walk across it without making noise but the squeaks help to point out where and when, in my movements, my leg is most wobbly and where I am rushing things.
It really does take about twenty minutes to cross my living room. I used a stop watch, after I wrote one of these posts, to time myself and came in at 19:27. That was a medium slow walk.
Another nice practice I like is to have a light source behind me and see if I can notice movement in my shawdow. I like that better than watching myself in a mirror, those are slow, slow, very slow motions. This is just practice. Most of the time it is not applicable, but it builds strength and teaches one to move at these extremely slow rates. In my experience there is nothing worse than being on a stalk and finding yourself lacking the strength and the balance right when you need it the most. ie; making it to within four feet of a friend without being noticed and blowing it right at the end. That is just losing out on the fun of being the one to surprise, it is worse if you lose your supper or become someone's supper.
Everything I talk about is taught by Tom Brown. He covers much more than this but there is a large network of people who get togther to practice this and more.
If you are near western Mass. there are quite a few groups in the area.

This is a link to a friend's camp. They do teach adults as well as children but they also act as a networking hub, though that isn't his primary focus.
Smoking is fairly simple, you stand in the smoke of a fire. It is best if you are clean first, such as having bathed and gone through a sauna or a sweat lodge. Rubbing yourself with local, fragrant plants also adds to the camoflage (prior to smoking).
When we camoflage we mud ourselves up before smoking.
I think camoflage is as fun as stalking, and as involved. It is a rush to lie part way in a well used trail and have people, and animals step over you or near you, with no hint they have seen you.
I have only done this with groups that knew I would be there, so there was little danger of actually being hurt by a runner or a bicyclist, but I have heard of, and read reports of, others who have been run over.
There are a lot of people who are very much more involved with this life style than I am. Rick's school attracts many of them.
Try braintan.com as well. Braintanners often are either involved with this or connected to people who live this way most of the time.
Good luck
