Very nice work. It looks like the sugarlabs website could use some better markup.

Re: Possible XO Graphics Optimization Technique
How did you do that? I haven't implemented DEC ReGIS or Tektronix 4010/405x graphics support yet.

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. http://mediamods.com/sugar/record_ui.html ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

But the XO is way more powerful (in particular the 1.5) so this is worth pursuing, IMHO: http://etoys.squeak.org/experimental/Etoys1968.jpg - Bert - ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
