The T. just posted one of his current projects.  Its called TouchAmp and it has brought great joy to our livingroom. 

We can now play music from our music library using an (almost) free touch screen interface.  We have a left over PalmPilot on our bookshelf connected to a mini-ITX PC that has our music library on its hard drive.

With the TouchAmp app, I can create and control a playlist.  For example, I create a workout playlist from our library that I use for my workout in the morning.  If I've picked a song that's too slow then I can move forward to the next one.  I can also add songs at the end if my playlist ran short. 

I love it because:
1. No PC monitor in our livingroom.  I look at a PC all day.  I don't want to see one when I'm listening to Arcade Fire.
2. I can control the playlist without leaving the room.

To me, a good playlist is the key to a good time.  In fact, the T. and I now compete on who can create the best playlist.  We take turns on picking tracks and trying to find great song combinations.
