The two-part work P: E(N_E) L-R 1929-2334 is composed of the acrylic glass panels with notes originally created in Das 2^4-Erfolgsprinzip. The frequency of visitors of the two lifts at the dormitory base 11 Vienna is recorded in a long-term performance according to the 6 door colors of the house.

Also in base 11 the exhibition space Pferd is located, in which the panels are presented as transformed three-dimensional figures. Three notation areas per left and right elevator form parallelepipeds that are stretched between floor and ceiling on wire strings. In this way, a miniature of the two elevators is projected back into the exhibition space with the data of their use, shifted in time.
