Nice, but does it update automatically or require a refresh? Hung out on the page for 30 seconds and didn't see it change.

It does update automatically, however Bitcoin prices change pretty slowly, so it's not uncommon for the price to stay the same for awhile.

Bitcoin price doesn't really change slowly if you're following it live at the exchanges. You should try one of the above links. You'll see the price change every second at least even at the slowest times of the day.

The only issue is that Coinbase data lags behind the more active markets by a few days. Live data is better seen on sites like http://bitcoinity.org/markets

Fred from Coinbase here - this isn't true. Would be interested to hear why you'd think this though!

Also http://trading.i286.org/

Looks useful. I think the spinning animation could be removed/shortened (it might be a bit distracting in its current form), but other than that you did a great job!

I'd like to see it use BitcoinAverage.com for data I think, along with currency choices to display!

Good work though!
