I brought the camera back to Ithaca, and might try finding some film for the silly thing. There was apparently a company making 126 cartridge film as recently as 2007, so I may be able to find some. I'd be astonished if I could find flash cubes, too. I had a much better film camera before I left for college, a Yashica with an electronic flash. Not sure when I got that, or, for that matter, where it is. I have a simpler 35mm camera around here somewhere, and have been playing with a friend's Mamiya. I should really finish that roll and get it back to her!
There's really a goofy number of pictures of Magimatic cameras (and maybe some pictures taken with them) on Flickr!
