Two crazy ideas I had while in Sydney. I'm posting them here because I think they are worth discussing and there's pretty much no other way I can act on them.
1. A Google Maps-style app which showed real estate / rental prices as contours / altitudes / colour.
2. A OLPC application designed to let children make up their own games with their own rules and play those games with other OLPC-laptop owners. No clue how to do this.
What do you think?
