This is screen capture of a work I made in 2016 that was partially controlled by a neural headset. The headset was probably sending BS numbers, but I didn't know at the time. The player wanders a 3D world. Elements of the world and presentation are controlled by the data from the headset.

Here's the software: https://gamejolt.com/games/BE/207036 It works just fine without the headset just by replacing the data with random numbers.
