I have released another small update to the script. It has now been tested in IE6 and IE7 along with Firefox 2.0 and Safari. I have also added docs to the project.
I think this script should be in stable condition now. If you stumble upon any bugs or have any suggestions please post them in your comments to this thread.
You can find the latest version for download here.

Ajaxian posted the result from Nitobi AJAX survey. It is interesting to see the results from this survey. What caught my attention was the Javascript framework question.
What toolkits or frameworks are you using in your projects?
This was quite a different result than from our last survey.
Even though I consider Prototype and Scriptaculous to be one framework (since you can’t run Scriptaculous without Prototype) it is interesting how many developers are using these frameworks. Honestly, I wasn’t surprised at JQuery being at the top, it is a very useful toolkit and so is Prototype. On the other hand, I was disappointed that YUI scored so low. I think YUI is a very well thought out framework that can really provide a very solid foundation for web applications.
What are your thoughts? What framework/toolkit do you use for your AJAX application?
Complete survey results can be found here.

Firebug is the most useful Javascript debugging tool out there. Occasionally when doing a large piece of Javascript development I tend to use the console utility which cause other browsers (such as IE) to crash your script. So here is a small piece of code that I have found to be extremely useful in making other browsers immune to the errors. Simply add this at the start of your script and let the magic begin!
if (!("console" in window) || !("firebug" in console)) {
var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml",
"group", "groupEnd", "time", "timeEnd", "count", "trace", "profile", "profileEnd"];
window.console = {};
for (var i = 0; i < names.length; ++i) {
window.console[names[i]] = function() {};
}
}
I will be posting more Javascript tips in coming days.

March 17, 2008: I have updated the script again. It now supports <a> tags. More information can be found here.
After reading through comments on the original launch post I finally got a chance to update the ProtoFlow script for with latest changes.
It now has a better caption system. It now supports image Reflection!
Credit goes out to those who participated in original blog post with all the helpful comments and suggestions. I am using Reflection.js found here. Many thanks to the author.
So fellow developers/users as done previously please provide your feedback and comments.
You can find a better documentation here and code is located at the bottom of the page here

It has been a few weeks since my last post. I got busy with few other client work and didn’t really get any chance to polish up the ProtoFlow widget. So in order to get things moving, I am releasing the code under opensource. I know that there are many talented developers out there who would like to contribute to the code and help us improve it.
So without further delay here is the demo page and the zip file
I look forward to your comments and suggestions.
Update:
Here is the markup for the actual widget:
<div id="protoflow">
<img src="imgs/DSCN0940_91360.jpg"/>
<img src="imgs/stimme_von_oben_187192.jpg"/>
<img src="imgs/Tropfen_1_Kopie_201721.jpg"/>
<img src="imgs/farbraum_012_147508.jpg"/>
<img src="imgs/IMG_4906_199357.jpg"/>
<img src="imgs/Tropfen_1_Kopie_201721.jpg"/>
<img src="imgs/Fries_201253.jpg"/>
<img src="imgs/Fries_201253.jpg"/>
</div><ul id=”protoCaptions” class=”protoCaptions”>
<li>Caption 1</li>
<li>Caption 2</li>
<li>Caption 3</li>
<li>Caption 4</li>
<li>Caption 5</li>
<li>Caption 6</li>
<li>Caption 7</li>
<li>Caption 8</li>
</ul>You can now initialize the Widget (usually done on page load) via:
Event.observe(window, 'load', function() {
cf = new ProtoFlow($("protoflow"), {captions: 'protoCaptions'});
});
The options that you can pass in are:
options = {
startIndex: 2, //which image or stack should the widget focus on after init
slider: true, //show or hide the slider widget
captions: false //do you want to show captions?
};
In fact, the actual “holder” for the images can be anything. You can have a UL with a bunch of LI’s and all those LI’s would be used to create the flow effect. Captions are held in UL (I wanted to use ALT attribute in the images to hold captions but I think this way we can create a ProtoFlow effect out of all sort of HTML elements. Give it a try!
Coming Soon:

ProtoFlow - CoverFlow effect (or similar to coverflow effect) using Prototype & Scriptaculous.
Over the past day or so, I have been working on this class based on Prototype and Scriptaculous libraries that simulate CoverFlow effect found in Apple products such as iTunes and now standard feature on Leopard. I am far from done but the idea is to play around and learn so I am not in a big hurry to finish it off completely.
What is ProtoFlow?
It is a very simple class that would allow existing websites to just plug-n-play and create CoverFlow effect instantly. Here are quick features that it currently supports:
I will be releasing the code for this later on but do let me know if there are other features that you would like to have in this widget.
Here is a quick screenshot for you (click to enlarge):
