Psst… drag the screen down to close the lid. Hold still and it goes sharp.

How it folds
Recent MacBooks have a lid angle sensor. DuoLid reads it 60 times a second while the lid moves and drives macOS’s own live blur from it.
1Rest
Nothing happens while you work. The effect starts below 110°, or below wherever the lid last rested, so a small nudge is a small change.
2Fold
As you close it, blur climbs toward the top edge, the desktop swells 30% around the hinge, and the screen fades to black just before it shuts.
3Still
Hold the lid still for a moment and the screen snaps back to sharp. Opening plays the whole thing in reverse.
Install in one line
The script builds the app, runs its self-test, copies it to Applications, checks the lid sensor and launches it. Run it again to update.
$gh repo clone promenaut-chamby9/duolid && cd duolid && ./install.sh
Or hand it to your coding agent
Clonepromenaut-chamby9/duolidfrom GitHub (it's private, so usegh repo clone), run./install.sh --loginfrom the repo, and tell me the lid angle it reports. If it says the Command Line Tools are missing, runxcode-select --install, wait for me to finish the installer, then run it again.
Add --login to start it at login. Want a different feel? The knobs (blur strength, swell, where it starts, the still delay) sit at the top of DuoLid.swift. Edit them and run ./build.sh.
