1. A brainwave actuated apparatus configured to operate a multi-user game, comprising: a first brainwave sensor for outputting a first brainwave signal originating from a first user; a second brainwave sensor for outputting a second brainwave signal originating from a second user; a device operating in accordance with an input signal; a controller operatively connected to an output of said first brainwave sensor, an output of said second brainwave sensor, and a control input of said device, said controller adapted to: determine first characteristics of said first brainwave signal; determine second characteristics of said second brainwave signal; based on a summation of said first characteristics and said second characteristics, derive a control signal to output to said device; wherein said first characteristics and said second characteristics are intensities and wherein said summation is a sum of said intensities; wherein the device configures a multi-user game, the first user and second user being participants in the multi-user game, the multi-user game being a co-operative game having a goal condition triggered at least by the sum of said intensities being a defined brainstate; and wherein the device comprises at least one vibratory element, the at least one vibratory element capable of providing variable tactile feedback to at least one of the first or the second user upon the goal condition being triggered.
