Close your laptop and the screen leans away, blurring and dimming, like an iPhone Duo folding shut. Apple uses a hinge. Mac Duo uses the MacBook's lid angle sensor. Your laptop has neither, so WinDuo reads the angle from your webcam. Free and open source.

Could you build this?
Partial The UI overlay is standard Windows desktop code, but estimating laptop lid angles accurately and in real-time from webcam optical flow shift without high CPU usage requires non-trivial computer vision calibration and low-level Windows Desktop Duplication APIs.
What it would actually take: The project requires C# or C++ with Direct3D and Windows Media Foundation/OpenCV to continuously capture webcam frames at low latency. The hard part is implementing a lightweight optical flow or vertical template matching algorithm robust to dynamic lighting, background movement, and varying camera hardware, combined with Desktop Window Manager (DWM) composition or Win32 transparent window projection APIs to distort the desktop without self-capture loops.
