Hi!
I just developed a tiny simple service that synthesizes sounds in real time using mtgox socket API.
The aim is to give you (and me) a feeling of the current market situation: loud sounds mean higher volumes, higher pitch means growth.
Here is the link:
http://ansrv.com/listen_mtgox/You can use it in the background and feel what is happening without even watching the charts, or you can use it together with
Clark Moody's realtime charts. It may take some before you start recognizing the signals.
If people find it useful, I will probably improve it, make github repository, etc.
PS: I wanted to do it long ago, but when I saw
listentobitcoin.com, it motivated me and gave some technical hints, thanks!
