Since I really enjoy watching Youtube videos while zoomed in on my MacBook, using Ctrl + two fingers on the touchpad (or a scrollweel on an external mouse), I created Blacktube.

Blacktube lets you watch any video on a completely black background so you are not distracted by the text and other colors on the original page. All you have to do is copy the following bookmarklet to you bookmars bar and click it while on the video’s Youtube page.

  • In Mozilla, drag this link to your link toolbar or right-click and bookmark it: Blacktube
  • In IE, right click the link and then click “Add To Favories.” It will give a security warning, but this bookmarklet is safe to use. Choose a folder – if you have the links toolbar visible and choose the “Links” folder, it will be added to the toolbar: Blacktube

The resulting page will extract the movie you wanted to watch from the HTTP referer URL and display it on a black background leaving you with a completely quiet watching environment which is – in my opinion – very convenient for zooming in 🙂

Please give me feedback in the comments, on what to improve or if any bugs occurred, while using it.

The Domain and the bookmarklet aren’t active any more.
I’ve mirrored the code here for you to look at:

After finishing my university I now present to you my thesis.
Unfortunately it’ll only be useful for a small part of my readers because it is written in german. But who knows, if there’s enough demand I might produce an english translation at some point in time in the future!

The title of my thesis is
“Das semantische Web und wie Microformats die Entwicklung vorantreiben werden”
which roughly translates to
“The semantic web and how Microformats will help it’s advancement”
