This is the best explanation of the Moebius Transformation I've seen, it is also one of the most clear and elegant explanation of a mathematical concept I've seen as well:

The New Collaborative Encyclopedia of Life
The basic idea is to allow social features to make it easier to collaborate, have scientists to peer-review the various different input channels, and make it easy to keep the encyclopedia up-to-date.
What I liked, at least as I could see it from the video, was the way it used map mashups to give the meta information about the images of various species the users could upload. For example, having many users take photographs through mobile devices and upload them on the spot, we will have a good idea on how habitats of these animals interact with human habitats, as well as have a sense of their general prevalence.
There is a post on techcrunch about it, and the video describes the project quite well:

Story of Muhammad Yunus and the Grameen Bank
Muhammad Yunus is the recipient of the Nobel Peace Prize in 2006. He is the founder of the Grameen Bank, which is a microfinance institution that gives loans to the very poor. I found this documentary about his story of how Grameen came to be on dotSUB.com, a new video site that enables real-time subtitling of videos (so people who do not speak English can understand them). It is amazing to see how he started with loaning just 27 dollars in total to more than 40 people -- less than 1 dollar per person, and that is all it took to save them from poverty. You can read more about Muhammad Yunus, microfinance, and Grameen Bank on wikipedia.

Explaining the Semantic Web
This video explains the spirit behind many Web 2.0 companies and the ideas behind the Semantic Web for the new and the old, and I like it because it captures some of the excitement many people feel about it. It is a good antidote for cynicism. The author indicates that he will make more videos, which would be great.

Hydrogen Economy not a Fantasy
This video explains how the Hydrogen Fuel Cell works, and why it is not a far-fetched idea. It has been viewed very few times on Youtube, so I decided to feature it here. The idea of the hydrogen economy is of course not only a scientific idea, or a question of economics, it is also a policy option, with political implications.

First Post - Slingshot HipHop
A lot of videos and online content I see nowadays is huge corporations trying to sell me things, or personal videos made public. Although personal videos are indeed cute, sexy, funny and such, I would like to see some content that does not feature a suburban, developed-world teenager or 20-something singing, being cute, being depressed. However I do encourage expressing real opinions.
Considering twitter is catching on like wildfire, taking social media to a level of inanity hitherto unseen, I've decided to invite you to divert your eyes to things we think about less often, and things that are less inane.
So, the purpose of this vlog (video blog) is to bring to your attention voices that need to be heard more clearly -- that I feel are getting drowned in the sea of online media. If you would like to bring to my attention something you feel deserves more attention, please contact me. My aim is quality, and to provide the other viewpoint thus the name: The Other Channel. At times I will be posting things that do not reflect my viewpoint, but I do think should be viewed nonetheless.
The first video I will post is a trailer for a documentary from Palestine about Hiphop, "Slingshot Hiphop" -- they tell us that every wall has come down and so will the new one, that Arab girls want to be heard, and much more. Their music is pretty good.
Note that I think the young people who feel like 'the black people of the middle east' need to be heard, and how they choose hiphop to voice themselves and not something else. I am not debating the merits of their analogy, simply providing them as they are. Here is the trailer:
