it's the kind where you have to have a dark cloth over your head to focus it c:
Haha, awesome. Grow an awesome mustache and put on a suit and pretend to be from the 20s, yeah!!
And I agree with your comment about long-exposure shots and night photography. Still a clever idea, might I say; despite star trails never doing much for me. But, I mean, I do a lot of stuff with light trails and drain pipes, and it's too easy to just take a photo with someone writing their name, or doing something dull and being all like "oh look, pretty light trails!"
I mean, think about it artistically. You can do more with light trails than write your name.
There's one photographer here in Adelaide that has this really interesting technique of making a "ball of light" with long exposures, and putting them into his shots.
Like these (again, not mine):


I think it's done by simply swinging a piece of string with a light attached to the end over, and over.
Sounds time consuming, but it certainly gets a unique-looking result.
