When making the HyperCat this little idea popped up in my mind. If adding Mindwave to Processing was easy and python was almost trivial. So why not add it in Blender Game Engine. In Blender game engine it is easy to prototype small games as you can model and create game in same software.
This game was made in 4 hours of watching blendercookie tutorials and 6 hours of playing around in blender 2.58. I used also Attention from mindwave as that seems to be easier to control. (Maybe I should train little bit meditation). Here attention controls the flying force of butterfly.
When attention reaches 50 and over butterfly will flap its wings and gain some upward force. I created small park (still in progress) to explore. With few hours more I should have some kind of visualizer for different brainwaves that mindwave produces and included in the world.
Here is a video of game in action:
I will be adding the sources for downloads as soon as I get more done in the scenery and few effects that I want to create in there.
