Well I don't really found it useful. Ok, it's cute; I will give you this, but...

I have used different desktops and I have used every bell & whistle available. And I have really enjoyed them, sure, but just for three or four days.

I think there's a lot of movement in that scroll, it's battery consuming, and it just doesn't provide any help for the user.

But don't get me wrong, I think it's a nice project to test your design skills, keep up working =)
