Trust Razer to come up with something completely ridiculous that I need in my life immediately. Project Ariana is a projector that incorporates Razer's full-spectrum lighting system, Chroma. It uses a wide-angle lens to project images, but it seems there's no lengthy setup process required here. Ariana uses 3D depth-sensing cameras to detect objects in a room and adjusts for them accordingly so that it still projects a flat image. You can use Ariana as a regular 4K projector when you're not playing games. It looks incredible.
