Ironically I got bored with how things were going so perfectly with Lou's Senseless rEVOlution so I decided to try this ROM out.
The UI absolutely blows me away. Everything is so crisp and I really enjoy being able to change themes and wallpapers on the fly is also great.
You can find more info on it here from the MIUI site:
Thanks to the MIUI Devs for all their continued work and appreciated progress
