Bob Neale has very kindly allowed me to draw diagrams for another of his amazing transformation puzzles. This one is called Trading Places and you can find diagrams for it at http://www.origamiheaven.com/puzzles.htm.
The puzzle dates back to the 1990s but has not been formally published before. The solution is simple ... but may be difficult to find. Diagrams for the solution will be released in a couple of weeks or so. Meanwhile please try to solve it for yourself. Dave
