Is this a dagger I see before me?

This morning is the coldest of the year so far for us in Staffordshire. Outside everything is frozen. The grass is rimmed with hoar frost, the bird bath is a solid lump of ice, the yard an impromptu skating rink. This, I think is a day to stay inside.... crafting.....shame :).
First things first though, my garden visitors will need some water and fresh food. I have seen a very shy Robin about the last couple of days and want to encourage it in the garden.
By the time I'm togged up and out there, it has started to snow, just a tiny dusting. Having sorted out the bird table, I notice the the settled snow. It's so cold it isn't melting at all but there is so little of it there is not even a single layer. The individual flakes stand out like stars.....no not stars....is this a dagger I see before me?
They are the strangest snowflakes I've ever seen. They look like tiny double ended daggers.
Intrigued, I looked it up on the net and found these crystals form when the temperature is about -5C. Guess it hasn't warmed up here then :)
There is some really beautiful photography of snow crystals here SNOW CRYSTAL SHAPES
I had to laugh when I saw how many different kinds of crystal there are and thought about snow spotters with little books ticking off the kinds they have seen :). I'm sure plenty of people have a good giggle at me and my ecstatic reaction to going into my favourite craft shops and photographing the next thing I want for my burgeoning stash.
What about you, is there something that sets you off in an ecstasy of ooohs and aaahs?
(Apart from that, lol :))
