Quassel \o/
Certainly like my Quassel. While I don't have time to post about the awesomeness (and the downsides against command-line-junkies-dream IRSSI), I do require my theme to be online/available.

Based on Jussi's Darktheme (on the Quassel website) but a tad easier color contrasts in the main text area and back to default-ish colors in the nickname and chat-lists.
Edit: Bit of an after though, the font is Consolas (between 10pt and 12pt is nice) - typically MS font.

Darren Nolan: is a happy chappy that twiddles with everything internet, specialising in website coding (in all its flavours) and linux administration. He doesn't have a creative design bone in his body. He enjoys long walks on the beach, programming and coffee. We’re kidding about the walks on the beach, but he does love his coffee!
