Introduction
In an earlier post, I discussed some methods for stretching the limited c64 palette, which generate static patterns that fill a bigger part of the screen. Here, an animated approach for filling the screen with horizontal color bars is presented, the so called “persian rasters”.
Description
The basic principle is to divide the area to fill into “fins”. Each fin shows a part of the same big raster bar, yet starting at an offset. In each frame (animation step), the position of the bar shown in each fin is incremented by the same value. That's basically all…
Demo
preset:
palette:
fin height between fin increment inner-fin increment per-frame increment
palette:
fin height between fin increment inner-fin increment per-frame increment

Yep — persian rasters…
