SubNodes, by Berlin-based artist Sarah Grant, employs popular ''Raspberry Pi'' minicomputers as wireless access points, serving a website and chat application <ref>http://subnodes.org/</ref>. Smartphones, for instance, can be used to connect to the access point, from which is served a website, alongside simple chat application. The project provides complete instructions requiring minimal prior knowledge for deploying a 'SubNode'. Such 'SubNodes' could be employed inside weatherproof plastic cases, like tupperware or a plastic lunchbox, powered off solar power bank or voltage-converted car battery, and used to provide valuable information without need for the Internet. SubNodes can also be used in a mesh networking capacity, connecting to other compatible nodes.
