This  is a wonderful UI paradigm by Digia and quite innovative. In this  underwater theme, you have these set of 3D bubbles that we’d otherwise  associate with icons. And hey – the circle icon surround actually works  in this concept (as opposed to the now over used squircle). These icons  populate the screen with yet more contextual bubbles when touched, e.g.  hit contact bubble and get more contacts. These bubbles live on a 3D  panoramic seabed. Though you are swiping left to right, it seems as  though you’re not simply moving horizontally but rotating about a fixed  point (which is a nice change). These Bubbles can also then be moved  behind (looking smaller) or towards the foreground.
This cool custom UI is demonstrated on the Lenovo IdeaPad S10-3t  Netbook/Tablet hybrid and the Nokia N900. It’s great seeing this work on  the big screen as well as the smaller mobile display. The N900 looks  less responsive to touch though that might be due to to the IdeaPads  feather touch capacitive and the pressure touch resistive on N900 (as  often seen, resistive screens are also responsive it’s just that folk  apply the same pressure as capacitive and thus such input is not  registered).
What’s cooler still is that Digia claim it took one developer just  one month to create this and shows the fast software development cycle  and ease of use that attracted them to MeeGo.
