First a mashup of the, "100 Greatest Internet Videos In 3 Minutes! (with links!)" This consists of A: videos from the internet, and B: one person's opinion about said videos, so there's some pretty awesome bits and some pretty stupid bits, but it's definitely interesting seeing so much internet "culture" packed into less than four minutes. As an added bonus, this is the second version of the video, which includes links to the full version of most of the clips in the description.
Some geeky music videos:
One Winged Office: A Sephiroth Song: Apparently having to go into the office on monday sucks just as much for Sephiroth as everyone else. Not as good as Code Monkey, but hey, it's got Sephiroth :)
Cosplay Fever lip dub: It's My Life: A bunch of cosplayers at the MCM Expo (the London verison of Comic Con apparently) lip synching to Bon Jovi's "It's My Life". Needless to say there are a lot of awesome costumes.
The Magikarp Song: A Pokemon Shanty: Pretty darn silly, but it's cute :)
Finally, not as much fun, but worth talking about, Anita Sarkeesian/"Feminist Frequency" put together a "Tropes vs. Women in Video Games" kickstarter to fund a series of videos talking about the way women are represented in video games. A certain segment of the internet decided to prove that sexism wasn't worth talking about by... being sexist and misogynist assholes, in her email, on her wikipedia page, and on YouTube. She's currently about $140,000 over her original goal of $6,000, but if you want to tell all the harassers where to go shove it you could always donate a little more. The kickstarter is going for another 14 hours (till noon Saturday pacific time.)
