Show HN: I rebuilt the Flash app “Scale of the Universe” in WebGL
Loving this, really nice work. Works super smooth and even the music is quite nice!<p>A little bit of unrequested feedback:<p>- Allow me to drag the viewport somehow. A couple times I wanted see elements around to position them on my screen in perspective but couldn't do that.<p>- Allow me to stop the zoom out animation somehow. At the moment one move on my trackpad and I teleport from coffee bean to Rwanda. I can't stop this zoom animation. It seems that I have to go to Rwanda.<p>- Support retina screens. This might come in really useful. To do this (it occurs to me that you're using PIXI.js), when creating your app set resolution to  window.devicePixelRatio || 1. You might be on a devicePixelRatio === 1 screen and can't see the difference right but trust me it's there. You can test and see it on any modern mac or apple mobile device.<p>Sending you a digital high five of size of the observable universe.
