Hollowhead’s VR Time Machine is an educational virtual reality experience that empowers courageous time travelers to journey through various periods of Earth’s history. Think of it as a four-dimensional zoo, a living museum, or an interactive documentary. This VR experience gives the traditional three-dimensional virtual reality experience the addition of travel through time. It un-cages the animals and brings them to life, freeing you (and your students) to explore with them. You, the time traveler, explore ancient habitats and observe species – from the first bacteria to powerful dinosaurs to modern mammals – in action as they struggle to survive in their environment. Each life-form the time traveler encounters will have a corresponding recorded narration, playable on demand during the exploration. Our aim is threefold: popularize science, create an engaging VR-based curriculum for teachers to use in the classroom, and provide an awe-inspiring virtual reality adventure that everyone on Earth can enjoy!
