My experience told me normally that especially handicapped people like to experience and try to live in games like Second Life what they cannot do anymore in real life. For example it can be very nice for blind people to play in a MUD to socialize with other people, or for deaf people to play in Second Life.
It can also be very accomodating for people who cannot walk anymore and need wheelchairs to play Second Life to forget about that for a little while.
Well, but not all wheelchair users seem to feel that way; there is a usergroup of people who are unable to walk in real life anymore in Second Life who don't want to hide this behind there avatar, quite the opposite. They're saying this is an undeniable part of myself, of my life, whereever I am and I want to show it.
So they are going around in Second Life in wheelchairs, a very uncommon sight. I've seen such an avatar yesterday in the garden, it just happened by chance that I saw her and you rarely see such avatars at all. Why? Because most people want to be beautiful, want to forget about it, that's why.
So here is a picture of this avatar, I was quite impressed by the openness of the person.
