I'd also doubt this is the "first brain-computer interface that allows the human user to navigate a 3D space". Note: "real BCI" does not need to be bidirectional and may be accomplished via read-only EEG (as ones eyes and ears will be receiving information from the machine).
One problem with neurofeedback has been that the visualizations have been done using proprietary software toolkits which inhibits the ability of designers in working with neurofeedback specialists to create more engaging and intuitive imagery for the brain. I've been working on a small toolkit that will allow you to control events in a browser using canvas and websockets: http://vimeo.com/mindhead.

Would love feedback and/or development help!
