У вашего броузера проблема в совместимости с HTML5
WARNING. This video is of a rather old and crufty version of TukUI. Although the overall look of TukUI is the same, much has changed. I suggest downloading it (or it's sister project ElvUI) and giving it a go.

I've been experimenting with TukUI of late. I'm loving the simplistic clean look and the fact that customisation can involve the dark art of LUA editing caters to my inner geek too.
I'm running a couple of customisations and extra community provided mods to skin various things and make the whole package just right for me.
