Before penning Madoka Magica , Gen Urobuchi crafted an erotic horror visual novel for Nitroplus titled Saya no Uta . In the game, protagonist Fuminori Sakisaka barely survives a car accident that claims the life of his parents. When he awakens in the hospital he finds himself unable to correctly process the sensory information around him and instead sees everything as pulsing gore and monsters.

This would be a horrible fate for anyone, so of course dōjin circle "Akasuku Parfe" decided to recreate the effect using the Deep Neural Network, Unity, and HMD Experience. It can then be used with virtual reality systems like Vive to make players terrified of their own bedroom.

Would you give it a try?
