Team 1418 has released our UI code today which uses pynetworktables2js, see the attached screenshot. It's functional and quite shiny looking, though the code isn't as polished as I would like. A lot of the HTML work was done by a student who didn't know how to program at all at the beginning of the season, but I think it turned out pretty well and he learned a lot.
