FGDesktopLoupe is a desktop dimmer that will allow you to use a spotlight beam that follows your mouse pointer to focus on a part of the screen.
FGDesktopLoupe will allow you to easily set the size of the spotlight and the color of the dimmer background.
You can use CTRL ALT to open the settings window and CMD ALT to toggle the dimmer effect on or off.

Pretty for a Free app, but a few *tiny* changes would make it 5 stars
This is free and it works and it's pretty well, and I give the author a lot of credit. There are a number of tiny things that would combine to make it really awesome.
1: Save my settings, for the next time I run it.
2: Put the Settings / Preferences on the menu, in the same place as other apps, in addition to having it come up with CTRL-ALT.
3: Let me also set the color and alpha channel of the foreground / Spotlight itself. In my case wouldn't have the background be in shadow, but instead have the cursor have a yellow circle around it, mostly transparent of course.
4: Drop the "FG" in the name.
5: It'd be nice to have the option of it's icon living in the top menu bar, rather than a full icon in the dock. Some people might prefer the icon at the bottom, so it would probably have to be an option.
6: Include a checkmark to automatically startup when the machine starts, although of course you can do this yourself by right clicking on the icon and right-clicking to options. This would even more valuable if the author had implemented menu bar icon, since there wouldn't be any icon in the dock to right click.
For me, I'd like to use it all the time for cursor visibility. Yes, I know about the Accessibility cursor settings, but believe it or not I stil lose the I-beam cursor on dark backgrounds for example.
Useful, small, but minor flaws compromise it
Just what I needed for highlighting during demos. I haven't used it over an Adobe Connect screensharing session yet, so I don't know whether it will work well in that context. However, when showing my screen on a large monitor, this will help quite a bit.
- It would be handy to be able to enable/disable the functionality from an icon in the menubar, but the app doesn't use an icon in the menu bar.
- Thus, you need to launch the app to have the functionality ready, and quit it when you're done.
- You can't specify the on/off shortcut keys, and the ones (Opt-Cmd) chosen conflict with shortcuts used in other apps. This is one of the reasons you may need to enable/disable the functionality entirely, and currently you can only do that by launching and quitting the app.
- The name of the app is obscure, and since I need to launch it and quit it frequently, having a name that's easier to remember would be helpful!
Otherwise, the app is very simple and does exactly what I need.
Great, but could use some polish
This app is extremely handy when doing a presentation (especially over webex or on a projector). Would be a lot slicker if it had some animations. For example, fade the mask in, zoom the hole out (like an iris), etc. If it were possible to hide the mouse when the spotlight is on, that would be even better.
With Family Sharing set up, up to six family members can use this app.
