The big three-three? Wow, that IS a milestone. And what better way to celebrate than another thinly-veiled (in gold!) merchandising opportunity! It's the great Hello Kitty rip-off party, and everyone's invited, if they have $$$!
It's amazing that people see something like this and immediately say "it's a witch!" without looking for any other explanation. It was moving in a straight line, so I'd say it was on a wire, whatever it was. And the UFO club said it was humanoid? From that footage? How? It looks like a blob! Some people are so gullible and so desperate for evidence of the paranormal they will believe anything is true except that this is obviously a hoax.

I work at the NT (yes, really I do), and this installation is setting off my hayfever. :-(
