Back when I was in my 20's, I did a time-lapse study of a cactus seedling 
breaking ground.  The seedling was way too small to get the camera close, so I 
placed a prism adjacent to the erupting seedling and shot vertically downward at 
the prism.  I set the camera on a ring stand and took one or two shots a 
day.  Barrel cactus seedlings are very amusing -- nearly spherical with markings 
that make it look like a face, the two cotyledons on top are like tiny cat's 
ears, one of which wears the seed coat, like a beret.  That was many years ago, 
and the film is lost, alas.
