This pen is heavily inspired by this site > http://www.amplifon.co.uk/sounds-of-street-view/how-and-create/index.html. Make sure to check it out. I decided to rebuild one little element in CSS only and tweaked the animation a bit.
This is only draft, i will fix all troubles later (: Inspired by https://dribbble.com/shots/1788738-Lighthouse
