Too Long; Didn't Read
I was reading the excellent article by <a href="https://medium.com/@karpathy" data-anchor-type="2" data-user-id="ac9d9a35533e" data-action-value="ac9d9a35533e" data-action="show-user-card" data-action-type="hover" target="_blank">Andrej Karpathy</a> on <a href="https://medium.com/@karpathy/virtual-reality-still-not-quite-there-again-5f51f2b43867#.q8une69vg" target="_blank">Virtual Reality</a>. In his article he mentions many games that should be delivered with a bucket, because they do make people sick by using motion that our brains are not able to process. One reason for nausea is that our body gets contradictory signals from our senses and thus think we have been poisoned, and wants to get those mushrooms out before its too late.
