I recently bought a Holga.  Holgas take medium-format film.  Also, they are made of plastic.  Nothing digital about them.  The idea of Holga and Lomograpy, the movement 'behind it', is to bring back the warmth and unpredictability of analogue and 'alternative' film processing – that's my interpretation of it anyway.  The wikipedia entry for Lomography sums it up thusly: "Lomography emphasizes casual, snapshot photography. Characteristics such as over-saturated colors, off-kilter exposure, blurring, "happy accidents," and alternative film processing are often considered part of the "Lomographic Technique."^{[citation needed]} Users are encouraged to take a lighthearted approach to their photography, and use these techniques to document everyday life, as the Lomo LC-A's small size, simple controls, and ability to shoot in low light encourages candid photography, photo reportage, and photo vérité through the much-touted "10 Golden Rules."^[2]

Holgas and other Lomo cameras are notoriously 'finicky'.  They emphasize experimentation and also being open to unexpected results (or to your entire roll being garbage).  It was with this in mind that I snapped a few rolls with my newly-purchased Holga during a trip to the US in the fall.  Sure enough, much of it was garbage but I really liked how some of the images came out, especially the 'vignette' look that Holgas are known for:

I also really liked the 'delayed gratification' in having to wait for the film to be developed before seeing the outcome:  These days, we're so used to seeing immediate results from photography and other aspects of our lives that the opposite can be frustrating.  But there was an excitement and anticipation built up from having to physically take the rolls to a shop for processing and then returning to get the envelopes containing the prints, which I opened with glee.

I think 'delayed gratification' will continue to be a contrarian trend in other spheres.  In fact, the Slow Food movement could be considered part of this.
