hyalosign

plural hyalosigns

1. film theoryIn the context of Gilles Deleuze's film philosophy, particularly in his work Cinema 2: The Time-Image, a specific type of cinematic image that embodies a fusion of the actual and the virtual, often illustrated through motifs like mirrors or crystals. These images disrupt linear temporality, creating a direct presentation of time in film.

   This is a progress in relation to the opsign : we saw how the crystal (the hyalosign) ensures the correlate of the opsign and the sonsign.

   1989, Gilles Deleuze, translated by Hugh Tomlinson and Robert Galeta, Cinema 2: the Time-Image, Minneapolis: University of Minnesota Press, translation of Cinéma 2, L’Image-temps (in French), pages 272-273

   According to Deleuze, any shard of a crystal is a hyalo-sign (literally, a 'glass-sign'), which can either go opaque or clear, that is, it can act as transparent glass or as a mirror.

   In other words, opsigns and sonsigns stymie the seamless flow of actual image to actual image; while the hyalosign links the actual image to a virtual correlate.
