This design is an almost replica of the famous Putra Mosque in Malaysia, it was build in 3ds max and assembled in Unity 3D.

So note that you have to download the unity web player plugin, just install it and it will automatically work without restarting your web browser. It's a bit heavy in terms of size (around 50mb) and graphic quality so you need some kinda powerful machine.

Bare in mind the design can be optimized to run on slower machines and also there is an Android mobile version that can be downloaded here.
