It's a very easy to achieve, but beautiful effect. All images and objects with class .appear_randomly will appear in slightly random order.
My client wanted to make a transition between pages. I thought it would be difficult to do, but with help of Scriptaculous effects and Prototype's $$() function it turned out to be pretty simple.
The method I used is easy to use, unobtrusive and needs only one element which usually is already in the code – main div surrounding all page content.
Login window which appears on top of the content.
Login functionality is one of the gates to the members area. It should be provided in very accessible and clear form. I think that the best solution is to display a form on top of existing page, send the login request with automatically forward the action to the desired one.
The example uses Prototype and PHP, but it shouldn't be complicated to rewrite it for other software.
And hit [Enter]. Alert window pops up
The goal is to look if the modified Prototype actually works. Let's make an object hide and show on user action.
