That's an interested set of ideas, and I like the general notion of implementing an overlay plane.   I'm copying the games list as well, since this has implications for some of the persistent presence-based games that a few people have discussed in the past...

At a recent visit to OLPC it occurred to me that a freeform 2-D shared space would be a useful thing to have on the XO laptops.  As I thought about it more I realized that, with a rich enough set of tools, it could enable many kinds of creativity and collaboration. I've started writing up these ideas, with an eye particularly towards incremental development, at:     <a href="http://wiki.laptop.org/go/Flatland"> http://wiki.laptop.org/go/Flatland</a> and I'd like to know what you think.  How do you like the idea, and what would you add to make it even more fun and useful? The Flatland idea as proposed uses the overlay in a somewhat different way from the "bulletin board" design described in the OLPC guidelines. How much of the bulletin board design has been worked out in detail at this point?  On the one hand, I'm concerned that it may be confusing for the overlay button to bring up a different bulletin board for each zoom level and each activity, which is what motivated the proposal in Flatland for a single overlay plane accessible from anywhere.  On the other hand, I do see the value in having a shared space that belongs to each activity.  Can we have a discussion about how the overlay plane should work, and look for ways to integrate the approaches? -- ?!ng _______________________________________________ Sugar mailing list <a href="mailto:Sugar@laptop.org">Sugar@laptop.org</a> <a href="http://mailman.laptop.org/mailman/listinfo/sugar">http://mailman.laptop.org/mailman/listinfo/sugar</a> </blockquote></div>
