Irrational Exuberance is an experiment to probe the possibilities of full room\-scale VR and the HTC Vive, unfolding organically as you discover and engage with deep space phenomena\. Prologue is the first taste of the galactic fantasy, delivering you to a lonely asteroid in deep space, underneath comets and giant stars\. Irrational Exuberance has been an audience favorite at Sundance and the Kaleidoscope tour and praised as a defining VR experience by the media for its use of space, sense and setting\.   The full release, scheduled for late\-2016, will feature dramatic interactions, deeply\-immersive moments, and impossible vistas\.  Featuring:    UNCOMPROMISING DESIGN : Exclusively designed for room\-scale VR interaction, Irrational Exuberance is a non\-violent, organic experience that offers cinematic moments of space, solace and spectacle\.     AMPLIFIED SENSES : A highly tuned, evocative spatial audioscape takes audiences to the surreal depths of space, from crumbling meteorites to chiming ephemera to the distant hum of stars\.    HYPER PRESENT REALITY : Beautiful worlds, mysterious sensations, and nuanced interaction weave together to create a heightened sense and awareness of this alternate reality\.     COMPREHENSIVE PREVIEW : A short, but impactful experience that foretells the events of the full Irrational Exuberance release\.
