[OSM-newbies] Visualizing route relations

[Ævar Arnfjörð Bjarmason]

Is there a tool to highlight relations that works better than the
bult-in one in the rails port:
http://www.openstreetmap.org/browse/relation/37431 ?

I ripped off some of that JavaScript and made my own at
http://u.nix.is/powerade.html , the line showing the route is still
barley visible and I haven't found a way to make it more obvious.
