One thing I love about Android is the fact that you can change the user experience whenever you feel like it, and ROU Launcher wants to potentially be one of your choices. The new UI was introduced this weekend by a team of developers. These guys are working hard on making this concept into a reality. The UI takes a very minimalistic approach to things, and tries to give you only the information you need without the extra junk you don't want.
This concept would be really interesting to see come to life, but sadly the team needs more hands.
