This was a fun weekend project to grab images from https://source.unsplash.com
Once you enter your search terms in the terminal window, It downloads a random 2560x1440 image related to your query from unsplash to whichever directory you have the .exe in. It then applies that image as your wallpaper to any number of monitors you have connected. Once the wallpaper has changed, it deleted the image file from your current directory and closes out the program.
wallpaper.exe will launch a terminal window that will ask you to input some sort of theme. You can add multiple values by using comma separated values like this:
Input a theme (i.e. nature): green,forest
Please note that there cannot be any spaces in your input. You'll have to use something like:
Input a theme (i.e. nature): red,neon-lights
Your wallpaper will be deleted and turned black if you enter:
Input a theme (i.e. nature): green, forest
or
green, street car
