I love interface glitches.
I was walking on a hill in a snow-themed sim when I met a couple, then I met a strange thing. A right-click told me that it was an avatar – or that the Second Life application thought it was an avatar.
Actually it wasn’t, and it disappeared just seconds after I took a snapshot. By the way, the Profile belonged to one of the two persons I had met there a minute before. The texture of the object appear to be the same of the Snowboard Boots created by Eric Linden that I, and possibly other people on that area, were wearing.
