What a.....?

My ah-so-perfect-copy of the screen

Winter and dark evenings are coming, so I decided to google some intructions of usage of the pedestrian safety reflector. One of the firsts results was link to Liikenneturva's website (Liikenneturva is an organisation, which try to improve safety of traffic in Finland). So I thought 'there should be some proper information. I click the link and wait. And wait. And suddenly the screen goes black and two light green bars start to circle aroung the middle section of the screen. It do just that: around and around. It has been spinning now more than 15 minutes and only difference is that the bars are possible little thicker than in the beginning. Gosh, I can wait to see what happen next!
