Are these flying 3-D views standardized? Is there a common WebGL framework for something like this, which includes user interface controls? Something where we can just plug in our own data?
Why why why is the help menu bound to the mouse scroll? Bind it to 'h' or '?', or better yet, don't make it disappear. I had to reload the page to get it back.
I observed people using the tool before it was bound to the scroll. Almost everybody used scroll in attempt to fly forward, while WASD navigation wasn't obvious. So I decided to show help on scroll...
