The official events of the Second Life Fifteenth Birthday are over. Except for the "Cake Explosion" later this week, no other happenings are planned. But that doesn't mean the fun has come to an end. With fewer people around, the lag is less, and you can enjoy the exhibits more. Or perhaps there are some you haven't seen yet, some you want to see again, or both. Gemma Cleanslate has been going around the SL15B sims, and wrote on more exhibits.
