gpx-map-js

parses a gpx file, draws a polyline on google maps colour coded to speed: more red == moar faster

Two gpx files are included, and you can test this out at: http://amiel.github.com/gpx-map-js The gpx files were created with MyTracks for android on my G1 (cyanogenmod)

I'm looking for a better algorithm for translating the speed to a color if anyone is interested in helping with that.
