 Hello all:

 As many of you are aware, work is being done to improve the graphics
performance of various XO laptop platforms.

 So in an attempt to improve things further, I looked into optimizing the
data Sugar sends to the video subsystem itself.

 I think I have made some improvements, and put up some samples of my Sugar
interface work at http://www.greenfeld.org/1April2011/ .  Feedback is
welcome.

 But while I have drastically reduced the amount of bandwidth required to
display the Sugar interface, I fear I have significantly increased the
amount of power required for optimal rendering.

Very nice work.  It looks like the sugarlabs website could use some better
markup. (Sidebar at the end would make it more readable.)

How did you do that?

I haven't implemented DEC ReGIS or Tektronix 4010/405x graphics support yet.

 I have a version of Turtle Art that is working with the new graphics

Yes, power consumption has been one of our greatest concerns as the pixel to
semicolon bump causes some serious strain.

The XO tablet's gpu will probably handle this going forward.

Well, I tried it for Etoys. On a ca. 1968 terminal it's way to slow. But the XO 
is way more powerful (in particular the 1.5) so this is worth pursuing, IMHO:
