Hard Javascript/jQuery Animation (Spinner/Scroller)

Okay, I'm trying to make it so when you click a button it'll spin a div with it's randomized contents and it'll slow down on stop on a specified div, now I have no idea where to start,
Here is an example of what I'm trying to do,

Any idea how to start? what should my priority be, jQuery or Javascript?
Kind Regards
EDIT: I'm not asking for anyone to spoonfeed me code, I just need an idea on where to start.

The animation itself can be probably solved easily using JQuery Animate functions. The animation supports easing, and the "ease out" is what you need. With some CSS, you would create some kind of viewport, and move the elements from right to left until the animation stops.
Let me help you with some starting code: http://jsfiddle.net/dfevruws/1/
The animation command is very simple:
$(function() {
$( "#items" ).animate({
left: -2000
}, {
duration: 5000,
easing: "easeOutQuad"
});
});
Probably more interesting than this is how you handle the selected item, but this is a different story, you ask for the Animation.

JQuery ScrollLeft with easing [duplicate]

This question already has answers here:
TypeError: p.easing[this.easing] is not a function
(12 answers)
Closed 8 years ago.
I am trying to scrollLeft with an easing applied.
It scrolls just fine if I took out the ease
$("#content").animate({
scrollLeft: '+=' + $(window).width()
}, "slow");
But when I try to add an easing to the animation
$("#content").animate({
scrollLeft: '+=' + $(window).width()
}, "slow", "easeInOutBounce");
I get an error that looks like:
TypeError: m.easing[this.easing] is not a function
Any help would be appreciated

easeInOutBounce is not part of the default set of jQuery easings. You’ll need to include jQuery UI’s easing library to have access to this. Either just include the whole of jQuery UI, or build yourself a custom version of the library containing just the easing components. Include this after including jQuery and before your code.

You have to add 'easeInOutBounce' to jquery easing array, otherwise you only can use 'linear' or 'swing'.
There are plugins to add easing curves to jquery, jquery-ui adds many of them including 'easeInOutBounce'

I think you need the JQuery UI to have access to this kind of easing.
Source (JQuery documentation):
Easing
The remaining parameter of .animate() is a string naming an easing function to use. An easing function specifies the speed at which the animation progresses at different points within the animation. The only easing implementations in the jQuery library are the default, called swing, and one that progresses at a constant pace, called linear. More easing functions are available with the use of plug-ins, most notably the jQuery UI suite.

How to define easing option in jquery animation?

I need to set easing 'easeInCubic' on an animation done using jQuery.
Here my code:
$('#content-scroll-inner:not(:animated)').animate({ 'top': moveOf}, this.animationSpeed, this.cbEndAnimation.bind(this));
Trying something like
$('#content-scroll-inner:not(:animated)').animate({ 'top': moveOf},'easeInCubic', this.animationSpeed, this.cbEndAnimation.bind(this));
What am I doing wrong and how to fix it?

Use easing option to set easing effect:
easing: 'easeInCubic'
This way:
$('#content-scroll-inner:not(:animated)').animate({ 'top': moveOf},easing:'easeInCubic', this.animationSpeed, this.cbEndAnimation.bind(this));

Use easing
Optional. Specifies the speed of the element in different points of
the animation. Default value is "swing". Possible values: "swing" -
moves slower at the beginning/end, but faster in the middle "linear" -
moves in a constant speed Tip: More easing functions are available in
external plugins.
With animate():
$('#content-scroll-inner:not(:animated)').animate({ 'top': moveOf},easing:'easeInCubic', this.animationSpeed, this.cbEndAnimation.bind(this));
With addClass()
$('.foot').addClass('slide-down', 1000, 'easeInCubic');

use easing: and make sure to add jquery.ui.js in your script tag. Please read this documentation

Easing on Fixed Position Jquery

Is there anyway to add a easing to a fixed element?, I've been looking around and I can't find an answer. I really don't know how it would be, maybe something like...
$(window).scroll(function() {
$("#form").animate({position:"fixed", easing: 'swing'});
});
Any help will be appreciated ^ ^ Thanks!
Edit:Pretty much what I'm looking for is when user scrolls, the fixed element obviously will follow the window position, but I want to add is a little delay in comparison to scroll action with an easing effect

You'd have to make that div absolute positioned, z-indexed and without parent, then move it on the scroll event. You can know the number of pixels scrolled with scrollTop(). Something like this:
$(window).scroll(function(){
var offset=100;
//stop is called so easing doesn't affect while it is still scrolling.
$("form").stop().animate({top:($(window).scrollTop()+offset)+"px"}, 300, 'swing');
});

Try this instead:
$("#form").animate({position:"fixed"}, 300, 'swing');

From the jQuery api ( http://api.jquery.com/animate/ ):
The only easing implementations in the jQuery library are the default,
called swing, and one that progresses at a constant pace, called
linear. More easing functions are available with the use of plug-ins,
most notably the jQuery UI suite.
$("form").animate({position:"fixed"}, 300, 'swing'); //swing being default

JQuery animation: Is it possible to change speed during the animation?

I want to move a div down a page, and I want it to slow down as it reaches the target.
I tried using call back with recursive func but it doesn’t look smooth:
function MovePanel() {
sidePanel.animate({
"marginTop": newCurrTop
}, moveSpeed, function () {
MovePanel();
});
}
Is it possible to slow down an JQuery animation?
If not what are the alternatives?
Thanks.

The animate method takes a 3rd param called "easing"; learn about it here:

Easing can really bring life to an
effect. Easing controls how an
animation progresses over time by
manipulating its acceleration.
