I personally LOVE the interface for Time Machine and have done ever since I first saw the videos for it. It's just cool; with those windows positioned in 3D space, being able to "fly" through them and the little touches such as the stars moving towards you in the background. I want more of this in Leopard. I want more animations. I want more transparency. I want more graphical effects. But I know it's a matter of personal taste - some people just don't like over the top graphical snaziness. But having used Compiz/Beryl in Linux and Aero in Vista, I do! So what do you lot think; does the average Mac user yearn for more of this type of interface? Or has it crossed the line and simply become garish? Personally I can't wait to see what developers come up with when using Core Animation. I've been programming with Windows Presentation Foundation in Vista and it makes impressive looking user interfaces a lot easier to implement than before. It's just a pity that there seems to be hardly any new applications that make use of it - Windows developers have been given such a great tool and yet are not taking advantage of it. I have a feeling that Mac developers are gonna come up with the goods though ... I haven't had chance to start learning Core Animation in great detail yet (I've been learning Cocoa and Objective C as I've only had a Mac for 6 weeks!) but I've already got some great ideas and I can't wait to implement them.
