It's always good to see a serious themed music vid
Comfortably Numb is one of my fave Pink Floyd songs, too... I have to admit, though, that most of the images in your flash are not the first things I think of when I listen to the song normally, but... they were certainly a valid interpretation.
I got a bit tired of identical, quite-ugly, big-nosed, oval-shaped guys being ground up in the machine over and over again... in some ways that seemed a bit more suited to Another Brick in the Wall part 2, but... much of the parts of the factory... the gears... the teeth... the spikes... the mashers... were all quite well done. Minimal animation, but the way you used what little there was was good.
I also enjoyed the shading, the textures, and the colours. Very nifty art style in general. Aside from the little guys, at least. #;-}>
Umm... I coulda done without the burger eating thumbs-up at the end, though. I think I'll go eat some lasagna now. #;-}>
You should do one for Run! Another great Wall song.
