You aren't having fun on the internet until you've found a couple of good Easter eggs. They're all over CodePen if you know where to look!
Want an actual egg? You can grab a couple off the conveyor belt in Chris Gannon's Eggmatic 3000
Ever seen an egg like this one, from Sarah Drasner's blend mode demo?
I'd bet that you already follow the internet best-practice of trying the Konami code to reveal Easter eggs on every website you visit. If you need some practice, you can brush up on it in Manuel Schaller's Pen.
Sometimes the best Easter eggs are the ones that take a little patience, like Tim Holman's Story Button.
While you're on the egg hunt, don't forget: Tim Holman built the CodePen console too. 😉
