I'm sleepy and here is an icon.
It is a big icon!
I made it for my top-level "Programming" folder. The concept's close to the "All my Files" icon only, you know, about programming stuff.
The entire set is free to download for personal use from the attachment or from my website.
Oh, and, I'm using Learn Code the Hard Way as the base of my journey into programming. Wish me luck :)
