There are Dead Poets Society icons here, by mayonegg. There was also an old DPS set by kikithepirate that has since been taken down, but I understand that if you contact her, she will link you to them.
I have a set of Swing Kids icons here, and there should be more coming (from the rest of the movie, where his hair is shorter). I also plan to icon him in Much Ado About Nothing - I can comment again to this post when those sets go up.
