YouTube has long introduced ways for users to annotate their videos and add links to external websites, other videos on the site, and more...

Belgian electro band The Subs... use video annotations to spice up their The Famous Videocast project...

In the videocast, the band members point to other videos which (on YouTube, not when watching it here or anywhere else where it gets embedded) you can easily watch without having to jump to another tab or webpage.

If you don’t click, the videocast just keeps rolling, but if you do you can watch other videos and return to where you left off in the videocast with a single click.

Simple, but nice.
