Wow! Never tried this myself...sounds kind of fun. Might try it myself
first and then possibly with my group at the end of the course.
cheers,

no fancy equipment, just have them snap a shot while leaning to the
left then rock to the right and snap another keeping the subject in
the center of the frame - once in front of a computer they can learn
to fine rotate the images to correct for any horizontal rotation. (if
on a win PC, Irfanview does this very quickly). Then they can resize
to a about 600 pixels wide (depending on the screen res) place the
left photo on the right, right on the left, cross their eyes and see
the image in 3D. They'll also learn the 'rule' about interoccular
distance is rubbish and the wider the shots are taken, the more
immersive the 3D effect will be. Wide angles are particularly good
for this.
for those who cannot cross their eyes, that might be another lesson ;)
It's quite a feeling of success to make a nice 3D image and brings
greater depth to photography. And they'll also learn another thing -
often people new to photography will make the mistake of seeing a
feature of a scene and photographing it with their minds eye view,
later finding that bird or flower is tiny in the image, they not
having moved in more or chosen a longer lens to render their subject
as the main body of the image. When they do a 3D rendering they will
find this 'mistake' is less so as their brain kicks in and again
establishes a priority, enlarging the subject and brings it to the
fore - then comparing the 2D and 3D images (uncrossed eyes V crossed)
they'll understand better how the brain can get in the way of
recording an image well.
please don't beat the students if they cock it up.. I know the
temptation is sometimes strong, but it costs too much in tissues and
soundproofing.
