Code
Most of the code are javascript and some part of html and css. They javascript to manipulate the images, logo, and text. There are not that much html but they combined all of them to manipulate the images logos,and text.
User Interface - UI
The user interface is great. When I hover over some of the links it shows arrow that right or up. I think that is show great the website is design.
User Experience - UX
The UX in this picture is interesting. The great think about the picture is the background images are moving up constantly. I think that is great interaction.
Summary
This site is cool useful for mostly javascript, since I have not seen that much html. however I have seen many javascript examples. I think it is still usefull because we may need one day to use both html javascript and more to build a website.
