I had a walk around Second Nature inside Second Life. I had tried SL before some months ago and this time the experience was much worse. My avatar keeps freezing when I touch objects or when I stand around idle for some time. Some other times the avatar just freezes in flight and continues in the same direction until I quit. It was just unusable.
Here is a picture from an 3D cell in the Second Nature island.
