A half second hand-held whilst trying to update this thing. How I ever managed before without it,
I'll never know. But after a walk with the dog, in the quiet snow, it was beginning to run low on
power, and I needed to update it.

One miss-ticked box later, and I was having to synch the whole thing all over again. The colours
aren't there all the time, it was just an interesting effect from the polariser. Some sort of
scientific thing that I'm not going to bother explaining!
