How to use a lomography camera?

in

I'm doing lomography just for fun. And I plan on getting a mini fisheye one.
Is this kind of camera just like an old-fashioned Kodak camera where you have limited amount of film and have to process it somewhere?
If so, do I use the special lomography film? And can I process it anywhere?

Answer: 
You load film in the camera and that lasts for a certain number of exposures after which you unload it and get it processed and printed somewhere. Most of the cameras use 120 film, a number take 35mm film. You can use any film, not only the insanely expensive stuff sold under their own brand. All the lomo crowd pride themselves on the fact that all you need to do is point it vaguely into a direction and press the button. Apparantly the fact that you don't really know what will be in the picture or if it will be exposed properly is all part of the fun.
