clipscreen is a simple application that creates a virtual monitor that mirrors a portion of your screen. A green rectangle highlights the specified area.

Why's this useful? You can use any screen sharing tool (Google Meet, Microsoft Teams, Jitsi Meet, etc.) to share the virtual monitor instead of your entire screen. No need to share individual windows and having to switch between them, just move any window you want to share into the green border.

TinyWM is a ridiculously tiny window manager implemented in nearly as few lines of C as possible, without being obfuscated or entirely useless. It allows you to move, resize, focus (sloppy), and raise windows -- that's it! TinyWM's main purpose is to serve as a quick example of some window manager programming basics.

Usage:
Focus follows pointer.
Alt+Button1, drag: interactive window move
Alt+Button3, drag: interactive window resize
Alt+F1: raise focused window
