Often daily exercises and experiments.
Since all projects are in thier own directory and are basic enough to only use sass and browser-sync they can all share one node_modules folder, but have thier own gulp.js.
To get running, just cd into desired directory and type gulp to run everything. Pretty simple / lean setup. As projects get more complex I'm sure I'll add more dependencies and each directory will have it's own package.json and whatnot, but for now, it's nice and minimal.
I will do my best to add a short description and a link to a codepen.io for each project in a README.md file.
