Cathode Séance is a CRT-inspired surrealist style built around scanlines, dithering, pixel breakup, signal distortion, RGB displacement, posterization and degraded analog/digital textures, all within a limited color palette.
Rather than simply applying these effects as an overlay, the LoRA can integrate them directly into subjects, surfaces and environments; sometimes causing parts of an image to dissolve into raster data or corrupted signal while preserving the underlying composition.
Trigger: cath0seance
Useful prompt terms:scanlines, dithering, posterization, pixelated texture, chromatic aberration, RGB displacement, vertical signal streaks, signal smearing, signal distortion, signal breakup, horizontal tearing, analog video interference
Mix and match the effect terms depending on how degraded you want the composition to get. Sometimes I like to throw them all in there. 
(same seed, settings and prompt)
Suggested Settings:
CFG - 1 (adjust if NOT using a Turbo model)
STEPS - 8 (adjust if NOT using a Turbo model!)
Euler/Simple (or play around with different combos to see what you get)
