I have a public talk on galaxy interactions coming up in a couple of weeks. To illustrate Merger Zoo, I'd like to feature Zoo applications (surprise!). I would be interested in getting some screenshots of nice image/simulation comparisons to give concrete examples, so if people would like to post good examples, here, I'll gleefully grab them. (Thinking back, it's shocking how much effort a student of ours put in the early 1990s into an application that would do that comparison interactively simply from flat-disk simulations. Computing marches on!)
