The app that I'm writing is not really a game, so it doesn't *depend* on having high performance graphics. It's also going to run in a window most of the time. I'm looking at LWJGL because I'd like to take advantage of hardware acceleration if it's available. I also want a graphics library that lets me get away from the inefficencies of Graphics and Graphics2D.
Is LWJGL a good choice for this kind of thing?
sure! - then only think I can think of as an "issue", is the lack of icon support in the title bar. Take a look at puppytron on http://puppygames.net/
