I'm very sorry, Tappers. I meant for the following email to have been

Hi Kenn,

I finally got around to ordering some IR transmitting plastic to
put in some goggles I also ordered. I finished cutting it and
went outside just to be disappointed. All I can see is the sun.
It does not look like the goggles you guys had at the workshop. I
ordered what you listed below. My first thought was that maybe
you used something less thick, but I see that the company does not
sell it thinner. I can see really bright lightbulbs and it will
transmit IR remote controls so I figure I got sent the right
stuff. I am confused. Do you have any ideas or suggestions?

Also, did Brian ever post something online, in the way of
additional resources from the workshop? He wrote on the board
that he was going to post additional information at:
http://littleshop.physics.colostate.edu/climate.html
I still get that nothing is posted there. Do you know if he did?
Or maybe it is posted elsewhere.

Thanks!

For thermal IR, we've been using the FLIR i7 in our labs, and it
works great. No video output, but it is very easy to use, and
has stood up to student use quite nicely over the last year.
For video output (for use in lecture or such) we have a RazIR SX
which does have video output, and is quite easy to use. I have
found these both to be excellent cameras, both in lab and in
class.

For near IR, you could use a sheet of IR filter over a standard
digital camera? We've ordered this (http://www.eplastics.com/Plastic/Plexiglass_Acrylic_Sheet_Infrared_Transmitting)
through a local plastic shop for use in our labs. Just cut a
small piece that attaches over the lens, illuminate your area
with an incandescent bulb (sunlight is far better), and you are
good to go. The material also works well in a pair of goggles;
our eyes are just barely sensitive enough to register the near
IR. We have our students in lab look through this plastic and
see the world in near IR for themselves.
ThinkGeek does have this (http://www.thinkgeek.com/electronics/cameras-photography/e5b5/)
camera which I have been eying for a while now. it looks great,
but I have not been able to justify the purchase to myself yet.
