More than two months after Jacek Antonelli and team launched an initiative to create a more user-friendly, open source version of the Second Life viewer, cheekily dubbed Imprudence, the first release candidate is available for download. The UI improvements are not yet available, but, he says,
[T]his version does contain a wide variety of small improvements created by SL Residents — JIRA patches that LL hasn’t (yet) accepted.
Since it's not an official viewer, the team selected a new logo to replace Linden's eye-in-hand: seen here, the "shaka" wave from Hawaii. "As the symbol of this project, it stands for the relaxed and welcoming atmosphere we should always keep." Being from Oahu myself, of course I think that's the best sign Imprudence is on to something important. Or as Barack Obama and I might say, were we there, "Good kine li' dat, bruddah."
