Visualising the modes... Lydian

This is where you can see how subtle the differences between the musical modes can be. The Lydian mode scale illustrated below is almost identical to the 1st posted Ionian (natural major scale), except that the 4th interval (dotted green wave) is augmented (or a semi-tone sharper), resulting in a sound altogether unique.
The next on my list is the Mixolydian, which is also only very subtly different from the natural major. How reluctant the human mind can be to grasp subtlety. We're all 99.9% genetically identical, 0.01% different. Yet that 0.01% difference makes up probably 99% of our perception of each other. No wonder we're all crazy.
