Not sure if this thing has a name, it is the mascot for Nico Nico Douga - one of the most popular online video sites in Japan.Nico Nico Douga is a video-sharing site that was originally created as a mashup of Youtube and 2-Ch (Japan's most popular bulletin board system BBS). Think of it as Japan's version of Youtube but with comment scrolling (type in a comment and it scrolls by when someone else watches that video). Users can see comments of former users as part of the video.
You need permission to embed their videos, I don't have one, so here's a link to a sample vid: Danny Choo's Stormtrooper Dance video (notice the text scrolling from left to right)
