Perhaps it's because I don't know any of the park visitors featured in the clips. Or perhaps it's because I'm just a cold-hearted tech geek. But the element of the presentation which impressed me most wasn't the images of the children on the castle. It was the spectacular, "Inception"-like video projections that played with the castle's form itself.
The effects color the castle like a kindergartener's crayon picture, crumble the castle's walls in a pixelated dissolve and shoot fireworks streaming across the castle, which then continue as real pyrotechnics in the sky behind. Color me... impressed.
Update: Here's a video of the complete show, sent along by our friend Scott Joseph:
Scott writes: "This is so much more than a slide show on the walls. At times the castle seems to fall into a pile of dust, or go up in flames, or seem to launch one of its turrets into space. I gotta tell you, I'm pretty jaded about this sort of thing, and it blew me away."
