In another classic meditation on the concept of can vs. should, the streamer who made her name beating Elden Ring using her mind has once again made incredibly unconventional use of her Master's degree in psychology. Content creator PerriKaryal is back with by far her most dangerous experiment yet: a custom controller rigged to her literal head that apparently controls her actual real-life bodily movement to a degree.
As reported by PC Gamer, PerriKaryal's latest stunt involved hacking her own brain's balance system using a technique called galvanic vestibular stimulation. In a genuinely frightening TikTok video, the streamer attached nodes originating from a circuit board to her head as an off-screen participant appeared to literally control her movement using an Xbox controller. Apparently, the wires were passing currents through her head in different directions and causing temporary imbalance. This initial test, in which she failed to walk in a straight line against the will of her custom-made controller, was just the beginning.
