These storage media further increasedthe flexible use of Fontane’s archival items, because they allowed allkinds of differently sized material to be kept on loose sheets in unboundform. Receptacles filled with discrete textual objects, such as note closets( Zettelschrä nke ) and slip boxes (Zettelkasten), are advantageous storagemedia for compilers, for they invite the generative process of reshufflingsources and creating textual patchwork from new combinations. 56 Infact, Fontane used his paper sleeves like a large- format slip box. Inthem, he stored material for the Wanderungen, but also for novels,novellas, and autobiographical writings on individual sheets. 57 Theexample “Figur in einer Berliner Novelle” (“Character in a BerlinNovella”), a folio sheet from Fontane’s Nachlass, provides a glimpse ofhow he formatted his material and indicates how important he found itto keep it in slip-like form (Figure 3.2).

In late 2006, Eno released 77 Million Paintings, a program of generative video and music specifically for home computers. As its title suggests, there is a possible combination of 77 million paintings where the viewer will see different combinations of video slides prepared by Eno each time the program is launched. Likewise, the accompanying music is generated by the program so that it's almost certain the listener will never hear the same arrangement twice.
