    First, I love the Gaze Trace overlay, well done 🙂

    One thing I’d want to know is how it is able to draw transparent graphics that overlay everything (even the taskbar and fullscreen directx applications) ?

    It’s obviously not just a topmost transparent window given it displays even on top of fullscreen DirectX, but I can’t seem to figure out the right Windows APIs to use to make a similar overlay.

    Hi @wildpeaks,

    Thanks for your interest! Yes, it’s a very cool piece of code for sure 🙂

    The program was made in DX11 and C++, but you can get a good idea of the implementation strategy
