It's Christmastime, one of the few times where old-fashioned snail mail matters anymore. Some companies send clever cards, like the ones we featured yesterday. Other companies send ViewMasters, the old-school 3D viewer that told stories through a series of still film frames.
Casual game giant PopCap did the latter and delivered season's greetings featuring characters from some of their games. Another ViewMaster card serves as a teaser for the company's upcoming original iOS game Popcorn Dragon. It's a cute shmup that's due out in spring 2012 from the Bejeweled developer. With its movie-based levels, it wouldn't be surprising to see Popcorn Dragon out in time for the Oscars.
