The desktop kind. This inventive, gleefully manipulative techno-thriller opens with a nerdy blogger (Elijah Wood) waiting for a dinner date he won with the actress object of his fanboy obsession, when a menacing, all-knowing voice from his computer starts telling him what to do.

The found-footage-ish gimmick here is that the entire movie takes place on his laptop screen. It’s compulsively watchable for a while, but ultimately the clever plot twists stack up to the point where the gimmick becomes unsustainable, and I found it difficult to maintain the desire to keep up. Final twist almost insulting. Japanese title: Black Hacker. (100 min)
