Hi folks,
I've just released the first version of the pixel2svg tool.
It takes a pixel art image and converts it to SVG in a pixel by pixel fashion, creating a vector square for every pixel (i.e. it's not a tracing program).
The rationale is to be able to conveniently enlarge pixel art for printing, creating PDF etc., or simply to have a pure-vector representation of the image.
The tool is at

It's a command-line tool and currently requires Python, the Python Imaging Library and the svgwrite module to be installed.
If someone is interested, I could bundle up a version with all prerequisites included or even create a binary .exe version for MS Windows in the next release.
Regards,
