When you look at something you can interact with in VR, you see this loading animation for 3 seconds before it triggers a 'click' event. It prevents unwanted clicking every single thing you look at by requiring you to look at it for a few seconds. Kinda like a crosshair you see in computer games. What is it called? Does it even have a name?
I want to Google / CodePen a nice animation for my stereoscopic HTML5 video player but don't really know what to look for besides circle loading animations.
