| 52 | +## Animated wallpaper | |
| 53 | + | |
| 54 | +`plasma-wallpaper-neiam-moire` is a Plasma wallpaper plugin ("neiam | |
| 55 | +moire" under *Wallpaper type*, for the desktop or the lock screen) | |
| 56 | +that draws the moire live, with a halftone field, both, or fading | |
| 57 | +between the two. Everything drifts slowly and never visibly repeats. | |
| 58 | + | |
| 59 | +Its colours come from the waxx themes (dark, light, her, afterdark, | |
| 60 | +forest, sky, clays, stones, blueprint): the ground is `base-100` | |
| 61 | +fading to `base-300`, the moire `accent`, the halftone `primary`. It | |
| 62 | +can hold one theme, or follow the time of day through night, sunrise, | |
| 63 | +day and sunset themes, either by clock times or by the real sun at a | |
| 64 | +latitude and longitude. Between phases it blends by the sun's | |
| 65 | +elevation, turning the hue so the transitions pass through the purples | |
| 66 | +of a real twilight rather than grey. | |
| 67 | + | |
| 68 | +Settings trade smoothness for power: frame rate (30 by default) and | |
| 69 | +speed, where 0 holds a still frame and costs nothing after drawing it. | |
