I don't know if I'm late to the game, but many/most TLD's have been made available by now. A list of them can be found here:
Domain names with .photography, .video, .movie, .photos, .art (and many more) are now registerable.
I think it's pretty cool instead of the usual (and probably on-its-way-out .com, .org etc.)
They're only like ~20$ a year and I think well worth the money.
