I built a Javascript GML Creator. It's built to do one thing, and
that's record GML; accurately. It's unattractiveness is intentional.
Being optimized daily for more accurate tracking.
Here is a link to Media Fecades Festival 2010 Edition (Available until
September 15th 2010)

By that time Graffitar Sandbox will be completely integrated with the
GML Creator, which will be extended significantly. The finished and
optimized GML Creator will be released on Github within 3 weeks.
