Traditional eReaders don't feel like real books at all so designer Fabrice Dubuy created the 'TwistBook' dual eReader to simulate a paper book. Unlike traditional books, eReaders only have one surface to read on. Dubuy's eReader has two e-ink screens bound together in order to simulate the format of a paper book. Each screen is synced with the other so that you can simulate the feel of flipping paper pages.
In an effort to further enhance the TwistBook's likeness to a real book, Dubuy made the eReader customizable. The cover of the book can be customized by printing directly on it. As a result, users can pretend that they're reading any paper book while exploring a wide library of literature.
