Hold that thought. :-)

I thought the I-glasses blocked off normal sight.
Great for sitting in a chair, watching a movie,
not so great for walking around.  OTOH, this looks
interesting: http://www.vrealities.com/vr1.html

That is the issue.  Yes, it is wonderful to do it all
yourself.  But if it never gets done (as you note
above) or if it ends up costing more, was it really
the best choice?  Now with various HMDs costing ~500
USD, perhaps they more clearly fall into the buy rather
than build category for most people.  Each person has
to decide how well they want to treat their eyes, and
whether or not they are normally successful with hardware
projects they attempt.

Just to be clear, the eye-link is a toy costing around
35 USD, into which someone has found a way to put an
HMD.  Perhaps you meant the eyetop.

It seems to be the core tension on this list.  Lots
of people want to construct their wearable by hand,
hence endless messages about how to build this or
that with found objects.

IMO, if you're interested in using a wearable or
developing the software for it, buy rather than
build as much as possible.  With a QVGA HMD,
twiddler, and used laptop, you can go from zero
to wearable in 1000-1500 USD.
