I also recommend people check out the author's website: <a href="https://johan-nordberg.com/" rel="nofollow">https://johan-nordberg.com/</a> - it has quite a neat realtime chat interface.

1.7 GW power. Wow! That means about 1 ton of CO2 released per hour (according to: <a href="https://carbonfund.org/how-we-calculate/" rel="nofollow">https://carbonfund.org/how-we-calculate/</a>).
Beautiful design!<p>Care to share any of the details on the tech? Are you using each of the exchange's individual APIs to calculate the weighted average? Did you use any library or framework to help with websockets, or to look at the blockchain?<p>The meaning of "Estimated Money Sent" was a little confusing to me, even after reading the definition on the About page.<p>What do the scrolling numbers in the background mean? I imagine there aren't enough of them to be all of the realtime transactions happening on the blockchain. Also, I'm sure you know, but they overlap when showing as 600x120 in iframe mode.<p>Allowing users to embed the widget in an iframe is nice and a good way to spread the word about your site. Maybe unbury that from the About page and link directly to an 'Embed this' page from the main page, and (as silly as it sounds) use something like clipboardjs to make copying the snippet to the clipboard easier.
The amount of power we're wasting computing a giant rainbow table drives me mad.<p>We could at least burn coal to compute something useful.<p>I'm not dismissing bitcoin altogether as it brought a great deal of interesting concepts, in fact I even mined a very small quantity once uppon a time. But right now the whole hashing random number madness is mostly a waste of energy.<p>I don't think we should afford 1.7GW (apparently 500MW according to a comment bellow) of power as long as we're still burning fossil fuel somewhere on earth.
The money sent metric is interesting, is that what's actually going on right now?<p>I have a miniscule amount of BTC (currently 'worth' £20), I just bought it out of novelty really, never found that much of a use for it outside of buying gift vouchers.<p>Where is all this money going? People just trading the currency between each other? Retail?
Beautiful. I think text size should always be proportional to log(transaction size) for better visual processing. I notice once $650,000 which was indeed larger and slower, which was great, but would be nice if had text size function change over entire range.
I think near the "coins in circulation" as $ rate someone should add a big fat disclaimer: "AT CURRENT EXCHANGE RATE". I know this applies to every currency, but given Bitcoin's volatility, it goes without saying...
I usually use <a href="https://btc-e.com/" rel="nofollow">https://btc-e.com/</a> because it also offers the value of other coins...
