Oh! Duh. Thanks for fixing them Northern. The instructions are right there on the page. I always wondered how people get them to say something other than the actual address, now I know.
I don't personally find them creepy, I think they're beautiful. The spooky/creepy, to me, comes from the fact that these people feel some odd need to lie and hide when asked about the meaning, to the point of even denying that they're holding a religious ceremony. What on earth could it be if it's not a religious ceremony?
And spooky/creepy comes in from making it tense and silent and high-stress performance anxiety, at least that's how it was at our school - the kids - or even the parents - would talk or sing, or start crying, or a fight would break out, and the angry Waldorf teachers would act like heinous crimes had been committed and nobody would have any fun. Out in the parking lot afterwards there would be lots of kids melting down from the anxiety and fear, and parents saying, What was THAT all about?
The toy ones seem pretty funny to me. Our teachers would have thought those were not acceptable, it would take away the mystery or reverence if the kids could go home and play with it. Kids would right away have their Smurfs or their Barbie dolls walking the advent spiral, or Thomas the Tank Engine, or take it apart and the boys would start using the candles as guns or something - ruining it from the anthroposophical POV.
