Polarized light in.... beetles

From BBC

Under left circularly polarised light, which matched the direction of the helices, the beetles appeared "super-green", because, as Dr Srinivasarao explained, "there weren't that many other wavelengths of light reflected back at you".
That's just amazing. (see the post below for less natural example of colors from polarization of light)
