 * Oppose kind of a cool demonstration of the technology but doesn't really do anything special to demonstrate a leaf that a regular picture or video of a real leaf wouldn't while losing the quality of a real leaf. Cat-five  t  c   16:48, 24 January 2013 (UTC)
 * Comment: This barely illustrates the concepts of a voxel at all, and a micro-CT rendering of a leaf showing its internal structure would have much more EV. I've added it to X-ray microtomography, where it should be more illustrative. I'm also wondering what the colours represent. --Paul_012 (talk) 03:20, 25 January 2013 (UTC)
 * I suspect the colours are false colours, which is pretty standard - something meant primarily to distinguish features from each other, in this case, veins from leaf tissue. Admittedly, I'm more familiar with this sort of false colours from electron microscopy, where "colour" lacks meaning anyway (very small objects, smaller than the wavelength of optical light, are too small to have individual colour, but it's often beneficial to use false colour to help distinguish parts more clearly visible in 3D than 2D, and I'm fairly sure shadows are generated onto the 2D image created from the 3D information as well.)
