I have an Xbox360, not a PS3, but my friend let me borrow his PS3 and his copy of The Last of Us after he finished playing it, and I have to say that I have never had a game, let alone any fictional work, ever affect me emotionally in such a way. Oddly enough, the game made me come upon a...

This building gets pulled down and in a weird unexpected kind of blast everything shoots out sideways. The guy holding the camera gets knocked out and the camera is just lying on the floor but there's nothing graphic in the video. My mind is blown trying to understand what happened and how...

My roku device has a channel for wunderground.com, which shows the weather. But it also shows a time-lapse video of the past 24 hours in a local neighborhood. The caption says "Facing West," and you can indeed see the sun setting in the evening as you would expect. But in the video the sun...

Now this guy makes a video very similar to how Khan Academy would. But the difference is that he can actually put well printed equations( maybe latex) into it as well as circle things to monentarely highlight while not having to erase. So, any idea what software he uses? Is this even...
