Virtual world on mobile phones

Finnish company Sulake (well known for their Habbo Hotel platform) recently released Mini Friday, a Habbo-like virtual world that runs on mobile phones. What is interesting is that it's rather a research platform, an attempt that gears towards the following direction:

Mini Friday is a small research project on virtual worlds on mobile phones. We are trying to find out if real-time virtual worlds make sense on mobile devices.

Mini Friday is a very simple virtual world - one small bar for now.

Why do I blog this? a nice app to test, I am more and more thinking about preparing a research project about Habbo. This platform raises very interesting questions regarding to space and place issues that I am interested in. One of the critical aspects here is the way the real space (in which you move, with your mobile phone in your pocket) is intertwined with a virtual environment.
