Started exploring Burning Life 06, the SL version of the Burning Man festival. First place was a giant sphere, and when you're inside it it projects 3D bubble photos onto the inside so that you appear stood or floating above some RL location. There was a city (Paris?), a coast (New England?), an opera house and many more.
The next was a small garden with fish swimming in the lake. When you clicked on a stone you were transported to this vast space, almost llike a planetarium with planets, stars and other everyday objects (table, bed etc), suspended in mid air.
