Readers may be familiar with the annual Great Reno Balloon Race, which is held over three days each September. (The event's Web site provides more details.) The good people of Timelapse HD attended last year's event, and shot this rather spectacular time-lapse footage. I particularly like the night images, where the flames of the hot air burners light up the balloons from the inside. It's worth watching in full-screen mode.
There are more time-lapse videos at Timelapse HD's YouTube channel. I'll try to embed some of them in coming days.
