This is slightly off-topic, but this post makes me feel sincerely nostalgic for building games in Eclipse and Swing back in the day. Growing up, Notch's live streams[1] where he would code up a game in Java Swing for Ludum Dare were one of my first exposures to programming, and reasons for eventually studying CS. I wish there were some modern alternative to Swing that would be as simple as Swing, but would allow you to create games for the web.
