Looks like it'll be a lot of fun.
I just uploaded five shots I took with my new filter:
Regrettably it's too small because I put in the size of my camera's lens, 28mm. However, it's made for a camera where you can screw the lens in so I'm going to try to swap it for the largest they've got so I can just hold the filter over the end of the lens.
Not sure it'll really come into its own until the summer's here, though.
