first, here is how to write a dll that will 'hook' to all mouse events, even outside your application, and send that to your application
http://forum.codecall.net/pascal-delphi-tutorials/33993-mouse-hook-tutorial-delphi-codes.html

I'm writting the application that will use that dll, capture the screen portion under the mouse and display it along with the pixel color underneath

Full projects :
- MouseHook.dpr => MouseHook.dll
- MouseZoom.dpr => MouseZoom.exe
both binaries must be in the same directory when running

I would have been inclined to say it's not possible, as every applications can set it's own cursor and the OS is changing the cursor accordingly each time the mouse move over an application.

but I checked if someone has an idea about it, and yes, apparently you could implement a workaround by setting ALL system cursors image to the one you want.

I haven't tested any of it, and if you need help about that, post a new question
