9 Incredible CodePen Demos

CodePen

CodePen is a treasure trove of incredible demos harnessing the power of client side languages.   The client side is always limited by what browsers provide us but the creativity and cleverness of developers always pushes the boundaries of what we think the front end can do.  Thanks to CSS, canvas, and WebGL, we can do just about anything in terms of visuals.  The following are nine mind-bending CodePen demos that will put your jaw on the floor.

Playing Kid

This is a God Tier™ demo.  The 3d piece of the animation is outstanding but adding the user camera takes this demo to the next level.  The three.js library is incredible and just the tool needed in this demo:

Animated Cube Slider

Important to note that no JavaScript is required for this elegantly animating demo.  Especially nice is the shadow shown at the bottom of the cube:

RubiCSSCube

One of my life goals is conquering a Rubik's cube and thanks to this demo I finally can!  A small detail but I love the drag cursor as well.

SVG Flying Saucer

The truth is out there and that truth includes the fact that this demo's floating animation is outstanding.  No jank, no laboring, just

Marvel Logo Animation

I'm not a comic book collector but the animation within the Marvel text here makes me a fan.  Wow!

Look Ma, No CSS

This awesome wolf animation requires no JavaScript or CSS to run.  The animation is fluid and as impressive as any demo in the list!

Confettis Generator

I love the acceleration smoothness in this demo.  I also love that you can seamlessly increase the speed and confetti volume with seemingly no impact on performance!

Particle Island

Created by the same author as Playing Kid above, this demo features a 3d stage with clouds, an airplane, and a rotating planet with trees and running water.

Yoga!

It's mostly the imagery in this demo but it looks beautiful.  The axis folding of different parts is beautiful as well.

Wow.  WOW.  What a gallery is to artists is what CodePen is for interactive developers.  Let's let this act as an inspiration for us to up our visual development game!
