Peter Grabarchuk's Puzzle Book

Peter Grabarchuk, who has contributed some puzzles to Math is Fun (example: Unfold the Prism) has now produced a book called "The Simple Book of Not-So-Simple Puzzles".

You can see some sample pages from the amazon entry: http://www.amazon.com/Simple-Book-Not-S … 1568814186

(Note: I do not profit from this, just letting you know about it because they look like really cool puzzles)

Re: Peter Grabarchuk's Puzzle Book

I found another of his puzzles just now. It took me a while to figure out where I knew the name from.
It isn't as hard as some of his others, which is nice.

Why did the vector cross the road?
It wanted to be normal.
