By the time I got over to 22nd Street this afternoon, I'd just missed the 5:00 p.m Light Spectacular, but the fifteen minute wait until the next show just built up the suspense. While you waited, you could work a control box & push buttons to light up parts or all of Frosty, displayed on a large screen in front of the house. This kept me, & the two small children waiting with their parents, quite busy.
It's grand show, with music, lights & special effects, but best parts are when the faces at the windows appear. You laugh when you first see them, and like a baby, you enjoy them just as much again when they return. They're a formula for instant delight.

Update: For much better photographs, & a far more technically capable description of the Spectacular, check out John Huntington's blog Control Geek. I met John yesterday at the show.
