Astralium is a virtual dreamword and is developed by multimedia artist Sander Bos. From the start on he had the oculus rift in mind. These immersive technologies make it possible to completely enter a different reality. The aim of the project is to explore different meditative spaces that have a positive and healing effect on mind and body. It becomes a journey through a world before birth and after death. In this way you follow the process of reincarnation. The artwork is in some parts based on the Tibetan Book of the Dead. As you start at the centre of a mandala, you can choose to explore different directions that will lead to various worlds. You may also choose to do a guided meditation, wich includes very slow pased guidance through the different spaces, so you don't have to do anything except to sit back, relax and enjoy the beauty of the different environments. 
Astralium is in full development and recently passed steam greenlight, the aim is to release it on steam at the end of the year or at the same time oculus releases their consumer version.
