I'm using Bitcoin almost every day and sometimes it seems to take ages until a transaction gets confirmed. I often find myself checking blockchain.info times and times again, just to see if a new block was found.
So I thought that it would be nice to get notified with a sound whenever a new block is found. And that's exactly what
blockear.com does. Just open the site and leave it running in the background. Whenever a new block is found you'll get notified with a sound. Currently, there are 5 different sounds available (I personally like the "boom" sound).
The site should be working with recent versions of all major browsers. If you have any suggestion for improvement, just let me know.
