According to this post: viewtopic.php?f=42&t=10863 i've trying to implementiate this glitchy for xp, but i want some help. What kind of metric i must looking for? I've saw that desktop and explorer in both of os are similar or the same.

Do u think that the some visual effects from whistler are just dll's?

And i read on some forum that common tast from xp it's just web view. So i'm think that we can change the way to display it - just like in whistler.

You can change it by two ways. If you're a pro theme maker, you can do it yourself. You can also download a theme file. However, you can't change it in the regestry. If you try to change it in the regestry, you can hose your computer.
