I was at OLPC for several years and now I am a volunteer on the project. My home page can be found here: [http://www.media.mit.edu/~walter]

===Regarding the Sugar Labs Oversight Board===
 
While it has been my goal to help get Sugar Labs to a point of self-sustainability, I don't think we are yet at that point. My goals for 2010 are to focus on fund-raising and further refining the organizational and governance models.
 
A bit about me and my role in Sugar Labs: I was part of the Sugar team at One Laptop per Child that left to found Sugar Labs in March of 2008. I have worn a few different hats within the organization: activity developer, occasional contributor to Sugar core, member of the deployment team, the marketing team, and the activity team. I was a lead author of the FLOSS Manual on Sugar. I am presently the executive director of Sugar Labs. I also represent Sugar on the GNOME technical advisory board and the Squeakland board. I have been a GSOC mentor and am participating in several pilot deployment projects of Sugar on a Stick.
 
===To do===
* <strike>get Frame test set up in Peru/Uruguay/Paraguay</srike>

Some procedures for setting up the palette and the shade functionality:

make "s (1 + (:s *0.8))
make "r (:r * :s)
make "g (:g * :s)
make "b (:b * :s)
] [
make "s (:s * 0.9)
make "r (:r + ((100-:r) * :s))
make "g (:g + ((100-:g) * :s))
make "b (:b + ((100-:b) * :s))
]
setpalette :i (list :r :g :b)
end
 
to rgb :myi :mycolors :myshade
make "myr first :mycolors

make "mycolors butfirst :mycolors
make "myb first :mycolors

end

====Turtle Art variables====
 
Following the lead of Luis Michelena, I've added named blocks and stacks. I plan to add push and pop next, which should greatly expand the range of possible constructions.

====Turtle Art push and pop====
 
While it is not the intent that Turtle Art be a full implementation of Logo, but there has been some discussion on teh Sur list about adding some capability for passing arguments to stacks. (and to support recursion). I have added a FILO and push and pop blocks to enable this functionality. I am looking for feedback. regarding this choice.
