The Mindmerger is a project that offers experiencing a new sense, that arises through a collective neurofeedback. It's users engage using Brainduino Neuroheadsets, while a central computer receives and interprets their brainwave activities: audio-visual feedback is generated in realtime and reflects different kind of brainwave correlations between its users. The result is in its truest meaning a psychedelic experience, and serves as an inspiration for its users: is the whole greater than its parts?
