Below are some panels and UI sytems that I help design, and then worked with programmers to get into the game...There were a handful of initial designs and redesigns for every system, I'm showing these because these are closest to what ended up in the final game.
Here is a video with some quick animated mockups I created using Photoshop and After Effects... on top of game footage we captured with Fraps. This allowed us to quickly see how something might look before we got programmers involved.
