Back to the Future - Badges

Hey guys :P I was wondering, how many badges can be seen in the movie?

Roland made us a fantastic "save the clock tower" badge, and Sarednad is about to make a run of the Clara's brooch (please be interested in this xD) > http://www.therpf.com/f13/back-futur...brooch-186334/

There are the 3 badges on Marty's jean jacket too... Any other badges/pins?
Do you know where to get most of them?







Also, the 'Art in Revolution" is most likely to be something like 1.5" in diameter na?

Thanks :)!
