If we're going with a mushroom theme, I've got a couple I can provide...
The first one is an "accidental cha-cha" from 2005, done by a friend of
mine, who took several sequential shots of the same mushroom in a tree.
I noticed that two of them seemed to make a decent left-right pair, so
I ran them through SPM's auto-alignment, and then used AnaBuilder to
make the anaglyph with some filtering for ghost reduction. The
alignment is not perfect, due to a fairly large vertical shift between
the left and right shots. Still, not too bad for an accident! :)
The second one is a phantogram that I made in 2010, from a cha-cha I did
during a multi-day, multi-portage canoe trip, of a large mushroom found
on the ground right near the trail we were following on the shore of
Geejay Lake, Ontario. As an 8.5x11" print, it would be very close to
life-size.
