"Trash Talk" is a distributed mesh network of decidedly inexpensive speaker nodes that play audio messages. Each node contains a microphone and speaker, and can be used to program the message that will be rebroadcast by the network. With several Trash Talk nodes, one can easily and quickly deploy a freely accessible messaging platform in public spaces. Nodes are intended to be cheap enough that the deployments can be considered disposable, and usable in spaces where authoritarian presences restrict democratic speech.
