This is based on some things I saw floating around on Twitter and Hacker News, which ultimately were inspired by the post, Ray Tracing In Notepad.exe At 30 FPS by Kyle Halladay.
I would feel remiss if I didn't help Go programs join in on the fun.
¯\_(ツ)_/¯
Just use the provided io.Writer to do whatever you want. A demo of using it with Apex log is provided in cmd/demo/main.go.
writer, _ := notepad.NewWriter()
writer.Write([]byte("Hello, World!"))
Please don't use this for anything important.
