Chatty - expand and header transition

I have always been a huge endorser of spatial approach to interface design. Project experience tends to prove time and time again that the continuity of interface while transitioning from state to state eases the learning curve and helps to create a memorable experience. I try to follow this rule in all my projects, you can also see it in my recent shots.

This particular shot is one of my explorations of a sticky information header design, minimising on scroll to make more room for content browsing. Let me know what you think, and don't forget to press L ;)

Sorry for the terrible quality btw, here is the full version.
