Does anybody know where i can get a large image of this, or a tutorial on how to make it?

tnx

I don't know about the lines inside of it (you can probably use your imagination ) but here's a Gimp tutorial on how to make Aqua orbs:

http://gug.sunsite.dk/tutorials/cmarshall1/

You can probably adapt that to Photoshop pretty easily. Note that the Aqua orbs in the tutorial aren't quite the same as Apple's, but again you can probably adapt it pretty easily (I've done so for my game stuff).

Lots of other great stuff on that site too.

What do you think of this?

Might want to change the contrast a little bit darker.
(comparing between the first one you showed and the second)
The top on the first one is darker.

anyhow, It looks nice!
