During the neurofeedback you will see a flock of triangles - or boids - which changes colour and speed depending on the activity in different frequency bands. The UI also offers a few explanations, which are only available in German so far. You can find (and fork) the project and English explanations and how to’s on github though: https://github.com/StefanieStoppel/brain2boid
Hope you share your thoughts on it!
Btw: I included a recording for those of you who dont own a Muse, so you can try it out as well!
Have a good one!
