Little tactile cubes for e-books you can hold in your hand.
What is the core principle of your idea?
An object you can hold in your hand that represents digital titles.
Can your idea be applied to different formats (in a bookstore, at a trade fair, at a conference)?
Yes. There is a large list of options and formats that can be used for this format - to follow.
Would it be possible to turn your idea into a reality, or at least create a prototype of it, at short notice, i.e. by the Frankfurt Book Fair in October 2014?
What do you estimate the costs for the prototype or the final implementation of your idea to be?
Very inexpensive for both uses. Card and/or wood cubes, plus perspex display towers of different heights - floor standing - atrium height (for maximum impact!) and counter-top. Multi-packs (like Nespresso coffee capsule boxes) could be used for promotion and delivery.
