MORE DIY bondage tools and furniture?

Lauren already posted about a spreader bar (Thanks infinity, Lauren), and I got to thinking that there must be more creative minds lurking these forums. Does anyone have a DIY project they would like to share? Perhaps some instructions? I'm curious, because I'd love to make things that mesh well with my home. I am sure that there are some people who have gotten creative and this is a great chance to show off your work!
