Background — Windows Vista Animated Desktop

// 1. Background gradient var gradientRect = new Rectangle(0, 0, 1920, 1080); var gradientBrush = new LinearGradientBrush(gradientRect, Color.FromArgb(0x0A, 0x1C, 0x2E), // top Color.FromArgb(0xE8, 0x9B, 0x55), // bottom 90f); g.FillRectangle(gradientBrush, gradientRect);

The wave cycle completes every 30 seconds, orbs on 20-second offsets, particles continuous. 3. Technical Implementation (Windows Vista DreamScene) Format: .dream or .mpeg (Windows Vista Ultimate’s DreamScene feature required) windows vista animated desktop background

double t = (double)frameNumber / totalFrames; // 0..1 double waveCycle = Math.Sin(t * Math.PI * 2); // full cycle per 60s var gradientBrush = new LinearGradientBrush(gradientRect

using (var bmp = new Bitmap(1920, 1080)) using (var g = Graphics.FromImage(bmp)) // top Color.FromArgb(0xE8

// Wave offset: -12px to +15px int waveAmplitude = (int)(waveCycle * 13.5);
