This is a rapid-fire showcase of 10 different effects, 3 seconds each, at 24fps 1920x1080.\n\nEffects to showcase (3 seconds each):\n1. Plasma (classic sine sums)\n2. Voronoi cells (20 cells, edge mode)\n3. Spiral arms (3 arms, logarithmic)\n4. Tunnel zoom (infinite depth)\n5. Interference pattern (6 waves)\n6. fBM noise (5 octaves, domain-warped)\n7. Diamond/checkerboard pattern\n8. Aurora bands (3 bands)\n9. Concentric rings (bass-driven, 8 rings)\n10. Vortex twist (twist=4)\n\nEach segment should:\n- Use a DIFFERENT character palette (cycle through: PAL_DENSE, PAL_BLOCKS, PAL_DOTS, PAL_KATA, PAL_GRADIENT, PAL_MATH, PAL_STARS, PAL_MINIMAL, PAL_BRAILLE, PAL_RUNE)\n- Use a DIFFERENT color scheme (cycle hue offsets: 0.0, 0.1, 0.2, ... 0.9)\n- Burn the effect name in the top-left corner as text\n- Use glitch-cut transitions between segments (2-3 frames of random displacement)\n\nKey implementation:\n- GridLayer with Menlo font, md density (16pt)\n- val2char for palette mapping\n- hsv2rgb vectorized\n- Tonemap with gamma 0.75\n- Font: /System/Library/Fonts/Menlo.ttc\n- Cell height from getmetrics()\n- ffmpeg pipe with stderr to file\n- Print progress per effect",
