Okay, I don't know anything about Indigo Children, but watch this by Sir Ted Robinson about our education system:
TED | Talks | Sir Ken Robinson: Do schools kill creativity? (video)
He's VERY funny, VERY insightful...I know it looks long, but watch a bit, and you'll probably get sucked in.

It's about how our education system (in the USA) is geared towards getting kids in college, and how it stifles creativity, which should be as important as math and science, etc.
I guess I don't really buy the "indigo children" thing--not that I can't be wrong, or that I know that much about it, it just seems like one of those excuses to call certain people "different" or "special." The ADD phenomena is similar--I think there's more kids with ADD because it hasn't been around that long. I'm not saying it's not valid, but people use it as a crutch--my own sister for one.
But, if anyone has some compelling info to send in my direction, please do so.
