The Portuguese capital, Lisbon, has hills--lots and lots of steep hills--and a robust tram system that weaves around the highs and lows, complete with a whole tapestry of wires that crisscross above the tracks.
Those wires were the inspiration for LX Type, the city's spindly new "official font".
The site has the entire alphabet laid out in photographs with their corresponding graphic form. At first glance, they are pretty tough to parse, but you can soon get in the groove and the shapes and patterns become more clear. You can also try it out yourself, spelling out different words, with a little added bonus; each letter has the specific tram number and stop, along with a pic of the surrounds and a little tidbit of history to go along with it.
