AI Analysis

●●SolidEye CandyWizardryRabbit Hole

Live shader overlays on your entire screen; 20 built-in effects from CRT to anime.

Strengths
  • •Cross-platform native integration (XComposite on X11, ScreenCaptureKit on macOS, Hyprland decoration API).
  • •Impressive technical constraint: auto-compiles GLSL to MSL for macOS without manual intervention.
  • •Hot-reload and runtime parameter tweaking allow live experimentation without restart.
Weaknesses
  • •Narrow utility: eye candy for enthusiasts, but limited practical use beyond aesthetics and accessibility (nightlight).
  • •No performance profiling shared; full-screen shader composition on every frame may impact battery or frame rate.
