It's really pointless and superficial.
And false. What Jeremy Montoya said: it's bullshit.
I'll also say that the traits needed for someone to be classified as an indigo child is very vague, you might as well make the entire population 'indigo children'.
I looked into that during 2011 and early 2012, and most of it was rubbish. Indigo, crystal, and rainbow children are supposed to look so different--why haven't I seen any in real life or seen videos where such children were around? I saw images of what they were supposed to look like--and never saw them in real life.
