Making an object'c color (or ambient) negative is a good way to show
it through thick emitting and/or scattering media.

Use a scattering type 2 or 3. To make it more visible, lower
extinction. The docs say it's unrealistic but I don't think so;
fine-tuning the extinctino value can work very well for realism and it
should not necessarily be limited to the [0..1] range (though in this
case the lower the better).

The bamboo poles are too identical. Maybe randomize them a bit in
terms of thickness and segment length/position.
