It's scary when you try it for the first time...then the lights blink...then all of them blink, then you write some programs...and they work and you ask yourself...IS THIS REALLY HAPPENING? Did I get this right on my first try?? Then you build an Express and you screw up and realize you aren't as good as you think you are and you're more careful!!
Gotta love blinky blinky....crap...oh...wait...I fixed it...YEA!! It works!
