The web dev community is full of talented programmers, designers, and artists, always building new things and pushing the web forward. There are hundreds of interesting CodePen projects that people share every day.

In this article we will take a look at some of the most exciting CodePen demos that we think you should definetely check out.

Donut progress bar

This demo shows a progress bar with images of different characters from “The Simpsons”. The progress bar can be filled by clicking the arrows below, and everytime it changes, a new image is shown.

Energy 3

This is a fantastic and fun demo that shows multiple sparkles moving around in different directions and changing their color. It has some really cool animations, amazing movements and eye-catching colors.

This is a 3D model of an eye, created with WebGL and three.js, that follows the movement of your mouse cursor. It has high quality graphics with some very realistic shadows and lightning effects.

Some very interesting radial patterns, performing different types of movements. You can change the number of lines, step size, line width, draw speed and other properties. It is fun and you can generate a wide variety of graphics.

Live Screen Effect

This demo shows a laptop screen with the CodePen site on it, made with the matrix 3D CSS function. It works like a real website and you can scroll up and down, change the pages and view all the demos.


This demo takes you on a trip inside a virtual tunnel. You can look around when you move your mouse cursor. It has some high quality graphics with shadows and reflections, and keeps up a high FPS rate, without any lagging.

In conclusion

Looking on CodePen for inspiration is probably not a bad idea now days. We have been looking there for a long time and never get tired to see how inventive are developers and designers now.
