I particularly like taking two or three shots as fast as I can and getting an exaggerated stereo pair, like this for example (if you can 'parallel view' stereo, you can probably get this to work onscreen).
Here's one of mine, a stereo pair:

Mt. Lassen from the west, on a flight between Portland and SFO.
Very exaggerated stereo -- as though your eyes were as far apart as the plane traveled between shots. Very reduced size so it's viewable. Lassen's the white cone in the upper right.
What I haven't photographed and wish I had (maybe you have?)
Glories up close next to the plane on the evening fog forming over the East Bay hills, seen descending from the north at sunset on an otherwise clear day. (I thanked the pilot on exit, got the usual vague nod, then I mentioned the glory -- and his eyes opened wide and he smiled real wide and said "Wasn't that fantastic?")
Next week I fly Oakland to Denver, Southwest. Hoping for a window seat in front of the wing, of course. Which side??
