Show a running cat on the taskbar, the faster it runs the faster your CPU is.
The cat icons are by Kyome22 under the Apache License.
I found it very difficult to implement this as there was no documentation regarding tray icons in c. This project is a simple example of such icons and can be used to learn about them.
It works best using the dark theme.
(If you want to rename it you will have to compile it with a different name)
windres main.rc main.o
gcc main.c main.o -o mainmain.exe
