Real Career advice: Do NOT give any indication of leaving to anyone until all your digital stuff is backed up offsite and you know where all your physical things are located.
Maybe like the writer, you work for some unicorn with nice and generally well meaning people. They might let you do this. It's more than likely however that your two week notice will be immediate termination.
