This is one of the more interesting projects I've come across http://graciekendal.wordpress.com/
Gracie Kendal in SecondLife will switch places with her firstlife handler Kristine Schomaker. This is amazing since Kris is physically different. Hair, weight, risk etc. So when they switch many changes will take place.
Kris will dye her hair. Have a nose piercing. Change her diet to lose weight.
Now if you don't know Gracie/Kris she is an artist but I think you should take time to get to know this project. What would you be like (you in SL) if you suddenly were thrust into Firstlife?
What would your friends list look like?
Where would you shop?
Also, please go to kris blog and give her suggestions. Perhaps even help to support her.
