Marco's Comments:
This is a booklet with ideas for use of the "Reality Twister", the lens which alters perception of horizontal/vertical lines. I have the gadget, but never really used. I bought the book to see if there are any ideas worth using the trick.
After reading, though, I could not find anything to stand out. It has many ideas and many suggestions on the management of the lens and some funny ideas, but most are just puzzles.
One of the major defects of the lens is that is a one-on-one trick...
