I am trying to figure out how to make my logo scale down when i scroll down like this site http://non-poro.us/
can someone help me>?
the example you showed is done with Laytheme as well.
Did you check in his code to see how he did it?
Maybe he even might give you the code when you ask nicely. Mostly it works ;-)
Can you post the code that I can have a look?
