"Juice is typically auditory or visual... it's about maximum output for minimum input."  


-Martin Jonasson and Petri Purho


Hi! I'm Opher

I'm a creative developer at Eko


5 New ways to juice up your site

Starting from somewhere

1. Ambient Animations

Ambient animations make the experience feel dynamic

Examples in sites:

Media boom

Solstice Coil

Implementation: HTML5 Video

<video muted autoplay loop">
    <source src="video/ambientAnimation.mp4">

2. Particles

Particles add a sense of magic and mystery

They are an efficient solution to create atmosphere without spending too much time doing animations

Implementation: Proton

3. Camera Movement

Camera movement adds realism and drama to user actions


It can help convey meaningful actions, or serve as a reward for user action

Implementation: CSS Animation/GSAP

@keyframes shake{
    0% {  transform: translateX(0) translateY(0); }
    10% { transform: translateX(6px) translateY(100px); }
    25% { transform: translateX(-7px) translateY(-50px); }
    45% { transform: translateX(4px) translateY(50px); }
    60% { transform: translateX(-2px) translateY(-10px); }
    75% { transform: translateX(0px) translateY(5px); }
    85% { transform: translateX(0) translateY(0); }
    100% { transform: translateX(0) translateY(0); }

4. Physics

Physics add a sense of fun and excitement

It's a system that is familiar from real life,

but at the same leads to unexpected surprising results

It lets users experiment

Implementation: Matter.js

5. Interactive Video

Interactive Storytelling

Interactive video allows viewers to shape the story

$('button.tell_lie').addEventListener('click', () => {
    /* Viewer chose to lie - There will be consequences! */
$('button.tell_truth').addEventListener('click', () => {
    /* Viewer chose the truth - Was it worth it? */

Implementation: developer.helloeko.com

What is this good for?



User Retention

Don't overdo it!

With great power come great Clichés
