Another video from our pit stop during the @Vivaldi outing. Just a note, this shows only a small part of the lights.

About

I have been working with Web technologies since 1992. I have co-founded two browser companies, Opera Software and Vivaldi Technologies. I was CEO at Opera and I am CEO at Vivaldi. I am a strong proponent of open standards. I believe in building feature rich products that can be adapted to the needs of users without collecting information about usage. I believe no company has the right to profile their users.
