Dear Friends this is my first time in here. I have been given some sort of assignment to develop this applet.
http://www.somewhere-in-time.net/webdesign/japplet.htm
I have even no idea where to start. I have worked in asp and cold fusion. I am also average in java theoretically without any pratical experience.
I will appreciate your help.

Just kidding.
Do you know how to create a simple Java applet? Do you know how to display pictures? How much time do you have for this project?

It looks like the page that you referenced is just using an applet made by Anfy, a popular maker of web "image effect" applets...

You know what one of our senious programmer just did in like five days. I dont want to tell you how he did it.
He doestnot how it works.
When I asked the creater of this applet. Some Fuccio. He said he has used Sin/cos equation.
I dont have dead line for it , but still I want to do. Need help friends.
Again where to start.
Regards
Haroon

As I was asking before...
What part don't you know how to do? Do you have a specific question to begin with?

There's some cool image processing going on in that applet!
My guess about how it works is that you have a source image, and a destination image. The "flip" is an animated effect filter based on the source and destination. The heart of the program will be the methods that construct each frame in the animation. They are created and stored in an offscreen buffer, perhaps something as simple as an Image[], and during the animation sequence, each frame is painted to the screen, the thread pauses, then paints the next frame, until there are no more frames.
Of course, the "secret sauce" is the algorithm being used to create the animation frames. This is beyond me at the moment, but I'm sure you can find something similar to it if you search for image processing or image filter algorithms, specifically "image wipes." There's probably a whole bunch of books written about it, since they're also used extensively in movies, Flash,DVDs, etc.
I'm also sure it involves the kind of math I might have learned at one time but have forgotten...at the very least, matrix arithmetic for the transformations, probably integral calculus, and maybe even some differential equations!
