Dvein is a motion and interactive studio based in Barcelona. They make some awesome stuff, and you can see that in their portfolio. Some of their work I can't even tell whether it's real or not. Seriously.

Besides that, their portfolio is one of the most stunning portfolios I've ever seen. They have taken the 'interactive' beyond and made and awesome showcase of thei work. It's really worth a visit. Enjoy a little selection of their work! Cheers! ;)
