I’ve done it, I enjoyed it, but the cameras were on loan! Still got all the prints, though not online anywhere. (Heck, not on the computer either—and only a few of them were printed. They were for awesome photography class.)
I have a Holga, but stopped using it since I got a digital camera. . It took some great shots, and some terrible ones too. Take a look: www.lomohomes.com/lomo_b.
