Heads up! This blog post hasn't been updated in over 2 years. CodePen is an ever changing place, so if this post references features, you're probably better off checking the docs. Get in touch with support if you have further questions.
I love a good spiral Pen, and the CodePen community's come up with some great ones over the past few weeks! Here are a handful of my recent favorites.
Matei Copot's "Binary spiral"
Ragnar Þór Valgeirsson's "Spiral"
Robin Delaporte's "CSS Loader"
Raymond G McCord's "Sacred Spiral"
Garet McKinley's "The Void"
