I used to be well known for my contests. Here's a quick one - hopefully.

When out voting one day,

I noticed this crazy animation happening with the arrow.

When I clicked to vote, the arrow started spinning. I am not sure what causes this or how to make it occur again. It happened today so I made a quick video.

Well here - figure this one out and win.
