Look, I'm as stoked as the next guy for a gingerbread geodesic dome. And while I was gonna grouse about how Scout Regalia's $25 dome kit is pretty much just two pieces of cardboard, and how, really, the gingerbread panels aren't structural, but are just icinged onto the cardboard armature, let's face facts: the likelihood that you'd actually build a geodesic gingerbread dome without this kit are pretty damn close to zero. So Scout is doing the Lord's dome work here.
I will say, though it looks OK in the picture, that I kind of which they'd stopped decorating it about halfway through the video. It's like a kid's unexpectedly brilliant drawing, which they proceed to color in, because they don't know when to stop.
