About the Silk effect
Silk renders vertical bands of shading blocks, then bends them: every row is shifted sideways by a slow sine of its row number, so the bands curve and sway like fabric moving in a breeze. A second time-based term slides the bands horizontally, giving a sense of material flowing across the screen. The result is softer and more elegant than most ASCII effects, closer to a draped curtain than to a terminal. It pairs well with minimal typography and generous whitespace. Because the whole screen is covered, Silk works best in a muted color or behind a solid panel; white or amber at low speed looks luxurious, while pink or purple feels playful. Export a PNG at a large font size for a striking textile-like poster, or embed it as a slow-moving header.
