They have a laser focus on the next step in front of them combined with long-term vision. Most people only have one or the other.

From behind me, Bret said: ‘Watch this,’ and pointed a small green laser at one of the books. The spine – the physical spine – lit up and above the bookshelf the book itself exploded onto an empty swath of wall. The entirety of its contents, laid out page by page by some hidden projector. The laser tracked by some hidden constellation of cameras. In his hand, Bret held an iPad, and as he pointed the laser at various projected pages they appeared on his device. As he slid from page to page on the iPad, the corresponding pages on the wall enlarged. It was a way to view both the macro and micro of a book – the overarching structure of the whole and the minutiae of the paragraph. The margins, it must be said, were gorgeous.布雷特在我身後說：“看這個”，然後用一個小型綠色雷射指著其中一本書。書脊——實體書脊——亮了起來，書架上方的書本身爆炸到了一大片空牆上。它的全部內容，由一些隱藏的投影機一頁一頁地展示出來。雷射由一些隱藏的攝影機群追蹤。 Bret 手裡拿著一台 iPad，當他將雷射指向各個投影頁面時，它們就出現在他的裝置上。當他在 iPad 上從一頁滑到另一頁時，牆上相應的頁面就會放大。這是一種從宏觀和微觀角度看待一本書的方式——整體的整體結構和段落的細節。必須說，邊緣非常華麗。
