How to get the depth, color and saturation of Lomography with a digital camera?

I have been a Nikon DSLR user for a while now. Not a power user. I just had some extra money so I bought it a few months ago. I just stumbled upon a few lomo photographs and I was impressed with the kind of colors these photographs have. I have never really tried researching or knowing beyond what I know, to be honest. I understand the basics, lighting - aperture - shutter speed, etc so I can take decent photographs. But never shot anything monumental or different.
Is there a setting or any way by which you can achieve this effect with a DSLR? I know a lot of tradionalists hate Lomography for it's cheapness probably, so I wouldn't really be looking forward to comments critiquing Lomo itself (and digressing in a way.)
I use a Nikon D5100 with the standard lens kit. I feel like getting back into it all again! Now sort it out for me, champs.

Added (1). Hey James, thanks a lot for the link! I've actually come across that one.tried it, and yes, it's close. I'm going to continue using it. Is there more or anything different from others?

You can give your photographs that look in photoshop. Here is a link (http://www.digital-photography-school.com/how-to-make-digital-photos-look-like-lomo-photography) to a tutorial about how to do just that.

About the only way you are going to come close to the same look with your DSLR is to do this:

Get the cheapest PLASTIC UV filter you can find from Ebay that fits your lens. Actually get 2 or 3 of them.

Smear one with Vaseline or the like. Put some scratches on another. Smudge another up with greasy fingerprints. Use one filter or all at the same time.

Place your camera in MANUAL mode. Set the shutter speed to 1/125 and the aperture to f11. Do not change it no matter what your camera meter displays. These are the locked in settings of the typical Lomo camera. This will make your exposure be hit or miss just like it. Set your ISO to 400 and LEAVE it there. This will be like shooting ISO 400 film.

Set your lens to the 18mm focal length, which with your camera will be an effective 27mm, sort of close to the focal length of the lomo lens.

Your view through the viewfinder should be distorted enough so your compositions will also be hit or miss… Just like a lomo.

Place your lens in MANUAL focus. The camera will not be able to auto focus, and you don't want it to anyway. You need to guess at your focus… Just like a lomo.

Make a mask out of cardboard or something to place around the edges of your dirty filters to get a vignette.

Not much of a way to get some light leaks into the body, so we will skip that part.

And there you are. That should give you something close to the look without computer tricks.

Just get a Holga or the like and do the real thing.
