Landers' mosaic stands prominently in the center of the upper foyer of building S2|06 in which the large physics lecture hall is located and elegantly conceals the entrances to the upper rows of seats. Building S2|06 was built to replace Pützer's old physics lecture hall [2], which was damaged beyond repair by a wartime bomb treffer.

The mosaic is divided by vertical and horizontal lines that are at most slightly tilted. This creates an irregular grid of squares, some of which are filled with polished white or gray marble flakes, and others with a collection of small natural pebbles, small colored stone flakes, or glass flakes. The abstract composition is formally dominated by a gray vertical band that gives support to two black double fields. Smaller squares, kept in color, optimistically brighten the mood. To interpret the abstract map of the city hit by the bombing into the mosaic would perhaps be going too far – although at the time of the mosaic's creation, reconstruction had begun. However, on many plots of land ruins and mountains of stones still reminded of the war.

A similar mosaic by Lander, in a somewhat smaller format, stands at the entrance to the house at Heinrichstrasse 71 in Darmstadt. The large wall mosaic on the corner of Rheinstrasse and Kasinostrasse, which was created a few years later (1960), is similarly abstract. The city map interpretation is plausible at this point, and the more accentuated colors express a much more optimistic confidence.
