The GUI to end all GUI libraries (Let's Dream!)

[Lutger]

Another interesting idea is immediate mode gui. It basically means that 
no or almost no state is maintained, at least as far as the user is 
concerned. Instead, the gui is recreated as needed. I've been playing a 
bit with it and it works nicely, but somehow I had some trouble with 
more complex gui's.

Here's a link, the video is worth it imo:
