That sound is a shimmer. It's a comination of effects including delays, pitch shifting and very highly saturated and long decaying reverbs. The PitchFactor can emulate this to a degree with it's crystals settings. I do it by setting A10-B10 then A gets -2c and I adjust B from +2c for a standard delay or get the crystals going up higher, say around +720c for a higher sound. I then set the reverb saturation to 80 and the decay to 7 seconds. The delay time and decay are adjusted to flavor the sound.
This still doesn't quite compare to the shimmer sound is a strymon reverberator. This is really the sound you want. Check this out: http://www.youtube.com/watch?v=hmWBQgiqjtY He doesn't really turn on the shimmer until about 10 seconds and then keeps bumping it up.
