Removed value: -"Ready-made visual, for when the code has none of its own. pianoroll/punchcard/scope/spectrum draw onto the 2D canvas behind the code; hydra-kaleid (rotating kaleidoscope), hydra-pulse (shape driven by a rhythm), hydra-wash (slow ambient noise) and hydra-feed (the piano roll mirrored and trailed) are WebGL shader backgrounds. A preset fills the MISSING layer: a hydra preset is skipped only if the code already calls initHydra(), a 2D preset only if the code already has a draw method — so hydra-wash layers happily under your own .pianoroll(). Hydra presets are dropped for viewers who prefer reduced motion. Writing your own visual is still the better result (draw methods: topic 'visuals'; shaders: topic 'hydra')."
