Designer Sungwoo Park's prototype Eazzzy! camera consists of a USB stick with a lens and one button, and offers "the feeling of not knowing how your shots turned out à la analog film" with the convenience of USB transfer; not to mention a groovily ironic, retro-styled shape in several bright colours. And you can undoubtedly expect the images to turn out fashionably lo-fi, as you'd get that with anything of that size.
Though I wonder if it'd be just standard cameraphone lo-fi or whether they'd put an artfully crappy lens on the thing (as with cult film cameras such as the Lomo and Diana). They could, of course, program the firmware to oversaturate the colours, or overexpose the centre of the image and vignette the edges, though that would run against the cult of authenticity from which the lo-fi fad stems, thus being the photographic equivalent of alternative rock recorded for major labels in expensive studios, with special ProTools plug-ins thrown in to make it sound grungier.)
