Ok Go.... Watch This Video

You may already know the band Ok Go for their one take video on the treadmills, but this one is far more impressive. The timing involved for their Rube Goldberg machine is amazing and that alone makes the video worth watching (it also helps that it is a good song). If you are curious about how this was made you can check out Wired for details.

More TED Talks

As Puggling has posted before, TED puts on various presentations by famous (and not so famous) folk about very interesting topics, usually aimed at improving the world we live in.  Here is one such talk by a former Microsoft guy who has a HUGE variety of interests.  Topics range from penguin poo, to nuclear reactors to T. Rex bones.  Enjoy!

For a more serious topic on what needs to be done.  Bill Gates (you may have heard of him) gives a presentation on energy usage.
