I think this is the ultimate version:
I think it’s amazing!Mini Tangram Paradox (MTP) is truly a masterpiece that you and your audience will love.
Every MTP is made with top quality walnut, perfect for the performer and collector.
A wooden puzzle fits perfectly inside of a frame. The performer adds a new small piece, and he can rebuild the puzzle! Then he adds another bigger piece, and he rebuilds the puzzle again! The puzzle still forms the same exact size rectangle, and it fits perfectly inside the same frame!!
MTP uses a brand new method. There is no palming, no stealing, and no shell. And its size is so small that you can carry it with you anytime and anywhere!
How does this work??? I have no idea! It’s so clean!
