What does a web studio need?

As a matter of fact, the question itself is not new, after all many design offices are beating it, not only in Russia, but also abroad. However, the other day I came across a studio site with an interesting implementation of web pages. This can be a lot of talk, but it is better to look once. Maybe someone will say that this is not new, the button accordion, I saw the bourgeois there and saw something like this ... I dare to assure you that the idea itself is not interesting, it is interesting when its realization is visible.

Attention is now the main question: is it interesting and useful to a potential client what is implemented on the site of the Novosibirsk studio and how much does it improve the perception of the site materials?
