Description

The DiagramHow do you divide a line into three? Or five? Or seven? Is there a simple way to marry harmony and geometry? What is the secret diagram alluded to by writers of antiquity? In this groundbreaking book, philosopher Adam Tetlow reveals the long lost Helicon, the master diagram of the ancient arts and crafts. Watch in astonishment as this magical geometric figure produces simple fractions, musical harmonies, Pythagorean triangles, perspective, and more.

Lightweight Balls
Color: A.Orange+Blue+Green
lightweight but solid. Unfortunately, I can't bring to dog park for my dog to play with as the larger dogs will destroy them. Not for dogs that chew through everything.

Too big for puppies
Color: A.Green+Orange
The balls were a bit too big for my 6 month chihuahuas:/ they are as big as a tennis ball so puppies didn’t like nor play with them
