This is the testbot program being used to run many accounts with the first name mannequin, copying the avatars of those nearby. This was at the libsecondlife group headquarters in Hooper in the Second Life virtual world. This was just before the big commotion over Copybot got started, when it still carefree fun playing with the “bot” programs.
libsecondlife is a group in the Second Life virtual world with a core group of programmers working to improve, extend, and enhance the Second Life experience for users of Second Life by producing the means for the creation of alternate viewers and viewer enhancements for the Second Life virtual world.
“The means” meaning a network abstraction layer for the SL data stream.
(Edited to correct error in labeling the program in use as Copybot instead of Testbot. )
