Ryan Holiday writes about the spectacle:

it captures attention, sparks curiosity, and draws people in

At his bookstore they built a book tower of 2,000 books

it’s also probably one of the single best marketing and business decisions we made in the whole store. Because it’s the number one thing people come into the store to take pictures of.

The spectacle gets you noticed. It’s the hook.

The key is not to become a P.T. Barnum and have nothing but spectacle.

The spectacle hooks.
The substance lands.
