Hollow rock turns into a router full of survival info when you build a fire beside it
Keepalive is Aram Bartholl’s fake hollow boulder in the woods of Neuenkirchen, Germany. It conceals a thermoelectric generator that powers a router configured to serve documents related to wilderness survival. The router switches on if the rock is sufficiently warmed, say by a blazing campfire adjacent to it.
It’s based on Piratebox, a standalone Internet router project for file-sharing.
It’s not the only art/artificial boulder project, though: Ed Ruscha claims to have made an artificial boulder called “Rocky II” and hidden it somewhere in the Mojave, where it is visually indistinguishable from the surrounding rocks, making it all but impossible to find.
