One of my favorite novels, "House of Leaves" by Mark Z. Danielewski, belongs best in a book, which you flutter through, turn upside down and decode in mad layers. The core of it, however, is a spooky, spatially suspect house. Hollywood can probably handle that – and I'd go see the results – but it wouldn't be the same without the scribbled anecdotes, the cover and the spine.
Journey is an unfilmable video game, despite being rooted in a concept that's miraculously relatable and explainable (for a game). A slender being, draped in beautiful and unfettered fabrics, is drawn to a mountain. The beacon beckons not with words, but a language enmeshed with the world itself. Some designers show they care by putting a dot on your screen; others make you a mountain.
