…is ready to play with. The code is not quite ready for prime time, so please don’t base anything on it 
It works for me in Chrome, but for some reason with Firefox it works from a local disk but not from the site. Odd. I’ll debug that over the next day or so.

Looks interesting again. Especially the up-and-down effect for the camera when walking.
For some reason I get the trouble with Minefield the other way around: It works online (did you fix anything, yet?), but does not locally.
With your example as well as my own experiments Minefield/Javascript tries to interpret the content of the external file when loaded locally:
—-
Error: syntax error
Source File: file:///C:/myfiles/webgl/learningwebgl.com/world.txt
Line: 2, Column: 1
Source Code:

Must have something to do with the use of the XMLHttpRequest but I just do not get it.
Hi Peter — I haven’t changed anything since I uploaded it but I’ve now found that it works just fine from the website on my laptop, but not on the desktop. Really weird! Investigation needed.
I also see the syntax error when I load it locally, though it doesn’t seem to cause any problems with displaying the demo. I think it may be because XMLHttpRequest tries to execute anything it thinks is JavaScript. The hypothesis is that when it loads something from a web server the MIME type is set correctly, so it doesn’t try to interpret it, but when it loads it from a file, there’s no MIME type, it tries to guess, and gets it wrong. It sounds like a plausible explanation, anyway
