The pulsating wall

BioWall is a wall that pulsates beneath people's fingers, repairs itself and even selfreplicates, by EPFL researchers.

Visitors are invited to destroy certain parts of the machine and watch how it repairs itself all on its own, substituting cells to replace the faulty material. Since they do not have any specific function, these cells can replace any cell in the machine, just like original embryo cells. Every cell in the BioWall also contains every piece of information about the whole machine. Unlike a traditional computer, the BioWall therefore does not need a central "brain" in overall charge.
BioWall can self-replicate and in case of breakdown, it can generate a clone or a part of itself.

The Biowall is permanently exhibited at the Ecole Polytechnique Federale in Lausanne (Switzerland.) since 2003.
