well, two places:
Britta Gustafson on the animated silhouette film Prince Achmed. Good thoughts and copious linkage about the movie.
Some discussion at Paddy Johnson's of Mark Essen's videogame-as-art Flywrench. A tangle of misunderstanding and mutual suspicion among gamers, art worlders, new media people, and assorted freaks, some of it unkinked on the thread. My contribution was to mention the LSD game, quite simply the best-sounding video game ever.
