I also have the same desire to perform stage type illusions for my act. I have purchased over $600 worth of books and plans in the last 2 weeks alone. Osborne Illusion systems 1-4, "Device and Illusions" by Jim Steinmeyer, "IllusionBook" #859 of 1000 by Andrew Mayne (signed) and several others. I am searching for "packs small, plays big" without having to buy a moving truck to get my act around.
There are some great ideas in these books and I am anxious to begin construction. My first project is making a "BASE". It will be elevated off the floor and will be used for a variety of appearences and disappareaces. Also a set of stairs/steps for gaining access to the elevated platform/base. There is also something called "Flash Appearance" that looks fairly easy to construct and can be broken down for easy transport. There are some books and vids out there for making your own inexpensive illusions using household objects, like cardboard. The problem with doing living room illusions is you don't have a backstage to work with. The ceiling isn't designed for anything except holding the walls up. On a stage, you have the side wings, backstage, and overhead supports for assisting you do your illusion.
Right now I have a device called HANDZ UP that I use to perform illusions. Check it out at http://www.hottrix.com/html/HandzUp.shtml
. I even levitate myself using this gimmick. I love the reactions I get when I do these mini-illusions. It's got me wanting more, just like you!
