No, this is not an advertisment for Apple 4 GB iPod Nano Black, it’s about Oil Standard, a new Firefox extension which converts all prices from U.S. Dollars into the equivalent value in barrels of crude oil. Pretty interesting, now is it possible to pay in barrels oil too rather than using US dollars ?

Oil Standard is a web browser plug-in that converts all prices from U.S. Dollars into the equivalent value in barrels of crude oil. When you load a web page, the script seamlessly inserts converted prices into the page. As the cost of oil fluctuates on the commodities exchange, prices rise and fall in real-time.
