Life without flash: How to see youtube/vimeo videos

I use a script called tube:

#!/bin/bash
clive --stream-exec="mplayer -really-quiet %i" -s $*

syntax is important:

tube http://www.youtube.com/v/VIDEO_ID_NUM
tube http://www.youtube.com/watch?v=VIDEO_ID_NUM
tube http://vimeo.com/VIDEO_ID_NUM

New version here!
