This is where I am staring a new mobile version of cow.
Code is stored in GitHub if you want to help:
https://github.com/wolispace/creativeobjectworld
Its using node.js for the server and a mobile-friendly UI using jQueryMobile.
A little database hosted for free by link: mongohq.com
A little test server hosted for free by link: heroku.com
I doubt I will be able to migrate all of the existing objects over, but I will give it a try.
All you can do right now is click the login button to login as 'bob' and type simple 'list' commands eg: "list void" or "list openfield"
Early days - but progress is being made.
