(Feature Req) Animated Taskbar Icons

I would like to have some of my TLB icons in taskbar to be animated like "Windows Start Button" mouse-over.
Is there a way to achieve that? Or would you mind considering to include this feature in the upcoming versions?
It would definitely strengthen and revalue the image of TLB software on those computers installed.

True Launch Bar supports 3 state PNG as icon. This is not an animation but can be useful. I plan to make the support of the animation in the future.

Thank you for your future plans..
For now, could you be more specific on the "3 state PNG"?
Can you explain how could I do that?

As example I've attached the vista start button. Download it and save. Right-click the button you have to "animate" and select Appearance->Set image. Select the downloaded image.

Image contain 3 pictures for 3 button states: normal, pressed and highlight. So you'll get something like animation when you hover mouse on button or press it.

Setting appearance broke the left-right margin spaces on the taskbar. (My button was an icon rather than PNG)
But it worked, thanks...
