This piece below was described as being by a very young new artist. It is called Ohne Titel 2008, but as a lot of pieces are called that I suspect it means ‘untitled’!
This was beautiful, exhibited in a small room, it is a collection of boxes made by mirrors facing inwards and leaning against each other and unsecured in place with a light bulb inside. Prior to installation the artist had thought up the idea but not tested it out at all, so to start with the mirrors were too fragile and the light bulbs too powerful, so they kept breaking and need ing to be repaired.
