I am wanting to start building illusions, to start a stage show. Fortunately I have all the tools I need, being carpentry and metal working are other hobbies of mine. I have seen several books on plans for sale, and I am going to build something next month. Since you suggested the trunk, Mr. Bunnell, I think I will give that a shot first.
I have also seen several gimmick illusions that look neat, like the floating head in chair, and the like. I really am interested in the trick "assistants revenge". It looks like there is a lot of potential for creativity.
