Few days ago I posted on an application brought to us by Manu Krishnan, which uses the N95's and is called ShakeLock.

I managed to find out his website's address thanks to his post on Symbian-Freak, so I found that he's been developing another application, which is called Speaker. I did download it from his website, and I found it's Python based, but I simple can't run it. Hopefully someone will tell me what I'm doing wrong.
Anyways, here is a log of what his plans are:

• ShakeLock (Beta)
  • Current release version - 1.0.3 - go to SF forum to request for the app 
  • Current development version - 1.0.4
  • Release date - soon !

  • Devices supported - Nokia N95 - 1 (firmware v20 above), possibly Nokia N95 8Gb,Nokia N82
