Project Description:
I need to draw an animation (let's say a GIF) on desktop. So, I need a function that draws on desktop, behind the desktop icons. The main requirement is that the painting should be done flickerles UNDER the desktop icons.

These are the requirements:
* The painting should be under desktop icons
* Should work with modern operating systems (Win XP and up). On Win 7 it should work also when Aero themes are enabled.
* Do not use DirectX (if you want to use DirectX/DirectDraw, please inform me first to approve it)
* Do not use ActiveDesktop
* Flickerless. The desktop/icons should not flicker. The animation/video should plays smoothly at a minimum 30 fps
* The program should not hinder other applications or the usual way in which the user interacts with the desktop.

Hints:
The code for XP is not difficult. You can find it on internet. The problem is Win 7. Microsoft changed desktop's structure in Win 7.
As an example, here is a program that already does what I want: www . desktopanimated .com.
Maybe you can use WinDoze or ApiMonitor to see how they are doing it.


Deliverable:
* Delphi XE source code
* Some documentation
* A very small application (and source code) that demonstrates that the function works. Nothing fancy. It should paint a series of 3-4 BMPs to simulate the animation.

Please don't post bids over the maximum amount accepted.
