Check if Your Browser Supports WebGL
Click on the following link, http://get.webgl.org It will tell you whether or not WebGL is enabled on your computer. Hopefully you will get something like the image below, if so, you're all set to start playing EyeWire.
You probably got a message that says "Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card." That means that you'll have to configure your browser manually to enable WebGL. For instructions move to the next section.
If you get a message that says "Oh no! We are sorry but your browser does not seem to support WebGL" that means you've got to update your browser to a more recent version before you can enable WebGL. There should be a link under that message, or follow this link http://www.apple.com/safari/download/ and update to the newest version of Safari. After you've updated, restart your browser and move on to the next section of these instructions.
