One of the new features in Inkscape 0.91 is the new Trace Pixel Art feature that allows you to take a PNG or some other bitmap of pixel art and trace it neatly into vector objects.

Inkscape 0.91 has only been out for a few days, and this is one of the first tutorials that cover some of the new features in this release. Aaron from GoInkscape! has just posted an awesome little tutorial on how to use this new 0.91 feature.
