The Blend4Web team has created an awesome interactive greeting card for you to explore.
With this interactive 3D greeting card you have no excuse not to congratulate your friends, loved ones or those who visit your blog and favorite social account (Facebook, Twitter and so on). Try opening the presents, turn on the TV and even write a personal greeting!This app clearly demonstrates the limitless possibilities of combining traditional web technologies and 3D graphics. The interface for typing a message is implemented by using HTML and CSS while the message itself is rendered on the texture of the 3D object. In turn, generic video and audio files are played back in the virtual TV set. Animation, dynamic reflection, outlining the objects under the cursor, interesting particle and lighting effects - all these also work in mobile browsers.
The source files are present in the Blend4Web free distribution.
