I have been offline for most of the past month, so I have only just got around to noting the news about Kye. This site has been getting quite a few hits due to being mentioned in the OLPC news: Kye has been ported to the OLPC.
Kye might well be a very appropriate game for the OLPC, in fact; it's an innocuous child-friendly game, simple to learn but, depending on the levels you play, can be very challenging. And it seems in keeping with the intent of the original Kye (where the registration money went to Save the Children).
Mind you, the laptop will have to have a durable mouse if it is to survive kids playing RUNNER :-).
Coincidentally, it appears that the port was done by Chris Ball, who used to work with me at Netcraft.
