You can see the room on this post, and you are very welcome to visit it.
There are some really cool and funny features on Lively. You can, for instance, add furniture and drag them, change clothes and looks. But, the most intersrting feature is the ability to add a wall mounted screen to your room and show Youtube videos, photos, or just post a link.
I took me time to understand how I can make my avatar walk and how to add furniture and links, but after a few minutes I got the idea. There are already user guides for Lively. Some include screen shots and are very helpful.
The big challenge for everyone who wants to use this tool as a marketing tool, is to make people visit your room and not other rooms. I don't know yet how can I invite avatars to my clifinar room, but I have the whole weekend to test it.
