About this art instllation:

“In 1925, Freud wrote a text that compares the faculty of memory to a child’s toy known as a Wunderblock. It consists of a wax slab stretched with cellophane, upon which a text may be inscribed, and just as readily erased by lifting the cellophane layer up and away from the wax slab. In contrast to Freud’s model, in which the pressure of the act of inscription onto the cellophane surface continues in the direction of the underlying layer of wax, in „The Wunderblock, the original selection and entry of data has been concluded in the past. The movement originates from ROM and is held in RAM, before travelling up towards the surface. Quite independently of our own states of presence or absence, the installation searches and inscribes autonomously. One has the impression that the underlying textual sources can never be perceived in their entirety. Because the many texts fragments are inscribed and erased simultaneously, one can read a given fragment only with difficulty before it vanishes. The model of memory demonstrated here is at once highly unstable, fragmentary, incomplete, perishable and ephemeral. The sentence fragments appearing and disappearing on the screen describe a process of finding and loss, safeguarding and destruction.” (more)
