So, if you want to play your favourite song/movie on OLPC use Jukebox.activity. Started working on this for the last few days after Sayam pointed me to the activity. It was almost in a stagnant condition.
My PyQt mind was someway different than writing this PyGtk stuff :) Sayam helped a lot.
The following features added as of now:
Will do a formal release within this weekend. I have a .xo file ready for testing. Please provide your feedback :D
If you want to start writing your own activity , start from this.
