Mechanical Book is an array of plastic cylinders which are individually pushed up and down by the matrix of electromagnets positioned below the cylinders. When simultaneously in the up position, a group of blocks forms a letter, letters form words and words combine into sentences. Because the book is imbedded with kinetic and mechanical dimension, it dictates the rhythm of reading. Mechanical book incites contemplative reading as a challenge to contemporary fast tempo of information absorption. In the nature of technology, the book can also malfunction, thus making the reading of its content impossible. A defect might even be involved in it as a subordinate factor. The work was made in collaboration with Stefan Doepner.
