Ascii Wave 4

A dark, cyberpunk-themed shader effect featuring a deep navy-black background (#0b0f24) with a dense grid pattern of wavy horizontal lines in cyan (#16ded7) and white. The lines are created by ASCII characters (〜 and *) arranged in a repeating pattern across the entire canvas. Overlaid on this grid are animated sine waves at a 157-degree angle that create a flowing, undulating motion through the character field. The waves have a soft, feathered edge with 0.52 softness, giving them a glowing, ethereal quality. The cyan waves appear to modulate the visibility of the ASCII characters beneath them, creating a masking effect where characters are more visible within the wave paths. A subtle purple (#5413ed) color layer sits beneath the wave effect, adding depth. The entire composition is overlaid with a fine film grain texture at 0.05 strength, creating a subtle noise pattern that enhances the digital, retro-computer aesthetic. The effect has a strong vertical flow with the waves moving diagonally, creating a sense of motion and energy. The overall mood is technological, mysterious, and reminiscent of 1980s-90s computer graphics or digital rain effects.
