VARNA (Visualization Applet for RNA) (http://varna.lri.fr/) is a new tool for RNA secondary structure visualization and it has a lot going for it: open source, pretty structure rendering, export to svg/jpg/eps, interactive inspection of structure with change of layout algorithm (linear/circular/radial). And most importantly: it is so simple to use that it is actually practical! If you are a teacher/student in a class covering RNA structure you should really have a closer look at VARNA. As a researcher, it is very easy to store dynamic VARNA-enabled RNA secondary structures on your computer – and in some situations this is really what you want.
