This is the second largest aquarium in the world. Located in the Okinawa Churaumi Aquarium in Japan,the main tank called the ‘Kuroshio Sea’holds 7,500-cubic meters (1,981,290 gallons) of water and features the world’s second largest acrylic glass panel,measuring 8.2 meters by 22.5 meters with a thickness of 60 centimeters.The video itself was shot with the exquisite Canon 5D Mark II camera Jon Rawlinson. A 720p version is available for download,and so is a iPhone/iPod Touch version. Just make sure you watch it in full screen. I just love this video. I could stare at it for hours. (Found on Digg)

oh yes it is really a very cool video with equally soothing music.
good selection!
