Sensi Soft is a team of web developers who pride themselves on their ability to efficiently fix technical problems and improve accessibility.Their site is a flash-built menu screen that changes via directional areas placed at the bottom of the screen. Each menu has different contents (above image shows the "Overview" and "Our Team" buttons, whereas another menu has a contact list).

 Navigating between different menus causes a spinning animation that ends with a background image representing a different location and culture, such as London, Tokyo, or New York. Each background has animated elements, such as moving papers, cars, and flags. Each menu  also uses a different font and color screen, emphasizing the menu shift.

 Buttons provide subtle feedback in the form of box shadows and flapping papers that, when clicked, provide an animation of a paper flying out and taking up the majority of the center screen. There is a loading box for the text on the paper, which is scrollable due to the amount of content. The exception to this is the button between the navigation buttons - the "About Us" button- that rolls when hovered over, which opens up a menu of similar buttons.
