Brain powered video game controller

Hey everyone this is my first project but its a good one me and a friend of mine are trying to turn brain waves into signals a makey makey can read through an Arduino uno and the end result (in theory) should be a brain wave headset hat can play games an surf the web :slight_smile: . Its currently still in the rough draft but if anybody can help or give me ideas like a small box with lights to show which button is being pressed (since mm has Arduino capabilities) which can be helpful when using your mind as a controller :wink: .
