Poser *can* be used for serious things. I use it heavily in creating "interactive textbooks". (I also play with it even more heavily; in fact the play teaches me the techniques needed for the serious stuff!) For a fairly simple example, here's a demo of static electricity, used in an introduction to electronics for non-technical students. This is a flip-card animation; in the real multimedia program I don't use GIFs but rather a set of individual images that can be timed and sequenced by math functions to move in various ways. .......ockham
