From the Walljumpers project - "WallJumpers Project A chronicle of the development of WALLJUMPERS, a transmedia project (Second Life, Machinima, Documentary Film, Google Earth) to leap over the world's separation border fences. WALLJUMPERS is a collaboration between Peggy Weil and Nonny de la Pena." - from the project website, http://walljumpersproject.blogspot.com/
"Acknowledgements. The Wall Jumper, a splendid novel by Peter Schneider introduced us to the notion of wall jumping.
Mauerkrankheit/Wallsickness in SL received a merit award of Merit Award of L$50,000 (US$200.) from USC Annenberg School for Communications Network Culture Project, an initiative funded by the MacArthur Foundation. WallJumpers evolved from this earlier work.
For the terms Mauerkrankheit (wallsickness - the malaise afflicting a society encircled by a wall) an die Mauer in den Köpfen (the wall in the heads) we are indebted to Christine Leuenberger at Cornell University for her paper: Constructions of the Berlin Wall: How Material Culture is Used in Psychological Theory.
Salient Infinity built the original installation of the five border fences for the Network Culture Project. Reed Steamroller and Gianna Borgnine of Sand Castle Studios created the stick figure avatar and provided avatar animation and background assistance. Bernhard Drax, as always, immeasurable help in machimina cinematography and sound." -- also from the project website, http://walljumpersproject.blogspot.com/2009/03/walljumpers.html
