Well, the problem really isn't related to the animation...

Here, you bind the name 'oldRect' and 'newRect' to the awt.Rectangle
class, I believe you want to create instances of the class:

oldRect = awt.Rectangle()
newRect = awt.Rectangle()

newRect points to the awt.Rectangle class in your code, so here you
attempt to set the static member 'x' to a value, but the awt.Rectangle
class have no such member.

Something that will make you say to yourself: "DOH!" :)
