Retro music visualisations inspired by Cthugha and the Atari Video Music. The sound is drawn into an image that burns, flows and mirrors itself from frame to frame – rebuilt effect for effect from the original programs. And the first music visualiser for the home, Atari's Video Music C240 from 1977, comes back as a simulation of its circuit.

Modes

• Cthugha 5.3 DOS (320 × 200, 1995) – with all extras: palettes, pictures and translation tables
• Cthugha98 (640 × 480, 1998) – including its particle scenes and the 3D views of the 3dfx version
• Cthugha-L (Linux, 2000) – adapts to the panel size, with its 3D displays
• Cthugha-4-Winamp (640 × 480, 1998) – the Winamp/ModPlug plug-in: beat-driven, 3D letters spell the song title
• Atari Video Music C240 (4:3) - the Atari Video Music C240 (1977): diamonds, holes and rings in the colours of the music, with its front panel
• Mix – all of them in turn, with a short fade

Each panel remembers its own mode, so several panels can run different modes side by side.

Features

• True to the originals: same formulas, tables, palettes, frame rates and random sequences; bugs that spoiled an effect are fixed
• Fullscreen on one or more monitors (middle click or F11)
• Effect changes per mode: as in the original, after beats, every few seconds, on each new song
• Presets like Cthugha's CTHUGHA.INI, the classic Cthugha keys (press ? or F1 in the panel)
• Song title overlay in the original VGA font
• Automatic input level, so today's music drives the effects as lively as a well-set sound card did
• Optional CRT filter for every mode – RGB monitor or TV,
• Compatible with the Default User Interface (Default UI) and the Columns User Interface (Columns UI)

Installation
Add the panel to your layout: Default UI – category Visualisation; Columns UI – category Visualisations. Right-click the panel to choose a mode.

• New mode: Atari Video Music C240 (1977) – a simulation of the device's circuit: diamonds, holes and rings in the colours of the music, shown on a TV picture
  • Move the mouse to the bottom of the picture: the front panel slides in – press its buttons and turn its knobs as on the device
  • The same controls are in the right-click menu and on the new preferences page "Atari Video Music"
• New: CRT filter for every mode – RGB monitor or TV, set per mode in the right-click menu ("CRT filter (this mode)") or under Preferences > Fomalhaut > Modes
• The preferences page "Effect changes" is now called "Modes" and also holds the CRT filter
• Smoother drawing in large panels and in fullscreen
• Fixed: a help text on the effect changes page was cut off
