A wordspress theme or html template




I am looking for either a wordpress theme or an html template with behavior similar to this template:
http://demo.pixelthrone.net/?t=panic%20station&o=coming-soon. I wanted to go with this one, but the developer is not answering item comments, and I don’t have time to wait any longer.

What I need is the combination of the visible menu, and the content changing without the screen reloading.

I have looked through absolutely hundreds of templates and themes but can’t find anything similar.

If anyone has seen anything I would be so very grateful!
