- Bad Signal 3Background
A dense, retro-futuristic digital display featuring layered shader effects creating a complex visual composition. The dominant visual element is a repeating ASCII character pattern (@, %, #, *, +, =, -, :, .) rendered in cyan, red, and green colors across the entire screen, creating a classic terminal or matrix-like aesthetic. The characters are arranged in a grid pattern with consistent spacing, appearing to be approximately 65 pixels in cell size. Overlaid on this ASCII foundation is a CRT screen effect with visible scanlines running horizontally across the image at regular intervals, creating a 200Hz frequency pattern with subtle brightness variations. The scanlines have approximately 0.3 intensity, giving the impression of an old cathode ray tube monitor. A swirling color distortion effect in orange (#ff6600) and cyan (#00ffee) creates organic, flowing patterns that blend across the character grid with a 60% blend strength and 2.8 speed, adding dynamic movement to the otherwise static ASCII pattern. The CRT effect includes a subtle color shift (4.8 intensity) creating chromatic aberration-like artifacts. A checkerboard pattern with gray (#cccccc) and darker gray (#999999) tones provides additional texture underneath the primary elements. A faint sine wave pattern in white adds subtle undulation across the composition. The overall atmosphere is intensely digital and nostalgic, evoking 1980s computer terminals and early digital art. The color palette is dominated by bright cyan and magenta against a pure black background, with orange and green accents creating a vibrant, high-contrast aesthetic. The effect uses hardLight blending mode for the CRT component, creating enhanced contrast and visual intensity.

- Bad Signal 2Background
A retro CRT screen effect displaying ASCII art characters arranged in a dense grid pattern against a black background. The image shows a complex layering of visual effects: the base consists of a swirling magenta-to-blue gradient (from the Swirl component) that creates organic, flowing distortions. Overlaid on this is a CRT screen effect with visible scanlines running horizontally across the entire image, creating a characteristic cathode-ray tube appearance with reduced brightness and contrast variations. The ASCII characters (@, %, #, *, +, =, -, :, .) are rendered in multiple colors including cyan, magenta, blue, green, and red, creating a chromatic aberration effect typical of old computer monitors. The characters appear to have a slight color shift with red, green, and blue channels slightly offset from each other, producing a glitchy, vintage computer aesthetic. A checkerboard pattern is subtly visible underneath, providing texture. Cursor trails in cyan and magenta colors trace paths across the display, adding dynamic movement. The overall effect is heavily pixelated with a 128-pixel size, creating blocky, chunky visual elements. The scanline frequency creates horizontal banding that gives the impression of an old television or arcade monitor. The entire composition has a nostalgic, cyberpunk atmosphere with high contrast between the bright neon colors and the deep black background.

- Bad SignalBackground
A retro digital matrix effect with a layered composition. The background features a dense grid of small colored dots in cyan, magenta, yellow, and green arranged in a regular pattern, creating a pixelated texture reminiscent of old CRT monitors. Overlaid on this is a swirling gradient effect that transitions between bright lime green (#25f55c) and golden yellow (#f0bc22), creating organic flowing patterns with soft blending. The middle section contains horizontal scan lines that add a CRT screen authenticity with reduced opacity. ASCII characters (@, %, #, *, +, =, -, :, .) are scattered throughout in a monospace font, creating a hacker/terminal aesthetic. A bright cyan and magenta cursor trail effect is visible in the center-right area, forming a glowing path with gradient coloration. The overall effect is enhanced by a hard light blend mode that creates contrast and luminosity variations. The image has a strong retro-futuristic, cyberpunk atmosphere with high contrast between the bright neon colors and the dark background. Scan line artifacts and pixel distortion reinforce the vintage computer monitor aesthetic.
