Nice easter egg in youtube!

Big websites always like to put some easter eggs, and not only websites but games and different kind of things too, today i just discovered a nice trick in youtube which is kinda fun! 

the trick basically, is instead of the red line that shows how you've progressed in the video, you can make it a variation of colors that changes constantly and pretty fast, in the screenshot i have above is yellow, but it's actually not still, it changes, all you have to do is go full screen in a video to make sure it works, then type "awesome" on your keyboard and see the magic! well it may not be something that is so cool but you may like it and i thought why not share it!
