I have been working with VR for a while now, both at work and as a hobby.
At EvoBooks we have created edmersiv, which is a virtual reality educational experience. We have a virtual tour of the coliseum, a virtual laboratory and a lot of different experiences.
We also have a color mixing art game (where you use physics to bounce colorful balls on a canvas) and a geography game (where you try to guess where you have been transported to, on a map).
