Vrome is a very interesting project! What does it do? It brings Vim to Chrome!
In fact, I'm actually writing this Movable Type Open Source-powered blog post with gVim. Seriously - it will actually launch gVim for me, allow me to write a bunch of stuff, and then when I :wq, the text is posted into the textarea field. Wicked.
I'm not really used to the gui version of Vim, but I think I can dig it.
