Hello Julians, I have a shiny late Christmas present for you, complete with Julia-themed wrapping.
Blink.jl <https://github.com/one-more-minute/Blink.jl> wraps Chrome to enable web-based GUIs. It's very primitive at the moment, but as a proof of concept it includes BlinkDisplay, which will display graphics like Gadfly plots in a convenient popup window (matplotlib style). Shashi has some great ideas for ways to control HTML from Julia, and hopefully in future we'll have more nice things like matrix/data frame explorers and other graphical tools. (Incidentally, I'd also appreciate any feedback on the display system I've made to enable this, since I'm hoping to propose it to replace Base's current one in future) Anyway, let me know if this is useful to you and/or there are any problems. – Mike
