Is it? It looks like something you could code up in a few weeks.. just take a random brain model, make it semi translucent, then map the data inside of the model to a continuous 3d smoothed grid, and voila
I'm not an eeg guy, but do fMRI. The little video on the site did not give me an indication of what makes it notable or useful. Eeg researchers create heat maps all the time over electrode points. They also look at timeseries on those electrode points.
Edit: I guess tht focus is on presenting the data as it is collected. Not sure if that is novel or not, but that is more specific than I thought at first.
