I'll likely port this to Sugargame when I find time. Another is Yay! Bee See, an alphabet program for younger children. git://dev.laptop.org/users/wadeb/yay-bee-see I've been working on porting this to Sugargame too, and adding editing features (e.g. the ability to replace the images and sounds for each letter, and to save to the journal) For a time, Typing Turtle used cairo to render its keyboard with overlaid hand SVGs. git://git.sugarlabs.org/typing-turtle/mainline.git The last version to use cairo was v5.  I switched to caching bitmap images of each key and the hand overlays to make the keyboard keep up while typing at a reasonable pace. All of these would probably make a pretty good cairo performance tests on XO-1. -Wade On Mon, Jun 28, 2010 at 5:17 AM, Peter Robinson <<a href="mailto:pbrobinson@gmail.com">pbrobinson@gmail.com</a>> wrote: <blockquote type="cite">On Mon, Jun 28, 2010 at 10:13 AM, Dov Grobgeld <<a href="mailto:dov.grobgeld@gmail.com">dov.grobgeld@gmail.com</a>> wrote: </blockquote><blockquote type="cite"><blockquote type="cite">Not sure this is relevant, but I have found that for software rendering </blockquote></blockquote><blockquote type="cite"><blockquote type="cite">(without hardware acceleration) agg (anti-grain graphics) is a lot faster </blockquote></blockquote><blockquote type="cite"><blockquote type="cite">than cairo.
