This is brilliant and a great example of Projection Mapping techniques ... right up my alley ... wait until it hits 1min

I'ts beautiful, but not really biolouminescent, just an artistic projection effect

I agree with Pau.

For the benefit of other readers, I'll explain that the second link http://vimeo.com/113933784 is the "behind the scenes video" mentioned in the credits of the first link https://vimeo.com/115082758, where it says (3:25):

ALL LIGHT-EFFECTS WERE PROJECTED ONTO REAL PLANTS, ANIMALS AND OBJECTS. NO POST-PRODUCTION.

In brief, the artists set up a computer projection system and shined animated light onto non-luminescent objects so as to evoke (quite wonderfully!) an impression of bioluminescence. It's very much like a painting of a forest: visually compelling, but scientifically accurate only to the extent that the artists might have happened to draw it that way.

Indeed ... I was only quoting the story ... I wasn't trying to over complicate it ... the clue was in projection ... but the actual process of acheiving it is pretty simple (from my point of view) ...

In retrospect, it does look pretty simple (in concept...)

But when first seeing the effect, I thought I was looking at something like the result of merging two videos: one shot in dim ambient light, and a second shot with the same subjects and camera motion, using very long exposures in near total darkness so as to capture true bioluminescence. In that scenario, "projection" also made sense to me as meaning to computationally project one image onto the other.

So once again, "context is everything". At least until the video got to the live frog, at which point it became clear I was on the wrong track because there's no way that critter was going to sit still for two shoots quite some time apart.

Thanks for the link to the explanatory article.

I understand Rik ...

I have only played with projection mapping on buildings and other flat/slightly curved architecture (work related) ... I will now (when I get time) try this side of it, like these guys have done here ...
