My grandfather just passed his 91st birthday. His only regret about getting older is that he will never experience what it is like to skateboard or rollerblade. I would like to give that to him. My grandfather is a veteran of World War II, a former FBI field agent who fought against organized crime, a father of four, a grandfather of nine, and not only the most honorable, but also the most consistently jovial person whom I have ever known. When reflecting over his long life thus far, he was asked if there was anything he wished he had done when he was younger. He looked off into the distance, and after a long while, said, "Well, I'd like to learn to use a skateboard, or maybe rollerblades. Yeah, that might be easier on me." He smiled and we all laughed, but as we looked back to him, he said wistfully and without a trace of irony, "I really would... But sometimes I have to remind myself I'm not seventeen anymore." This is where I need your help. Earlier today a friend sent me a video of her bed-bound grandmother taking VR tours of distant cities to which she had never traveled. As she looked left and right, her expression became one of pure wonderment, an unrestrained smile spreading wide across her face. I want to provide the same experience for my grandfather. Does anyone have any recommendations for a performant VR stack, preference of VR make/model (HTC Vive vs. Oculus Rift), or knowledge of high quality content sources? With regard to price, I am on a limited budget due to recent medical expenses, but I earn a good living. So if there is one option that is clearly better, I would rather sell every luxury item I have than deny him the best experience. Thank you all for reading.
