Ah, I remember playing Nomic obsessively online back when I was in high-school. I was the webmaster (or "Secretary of Truth") who inflicted the painful red color scheme on MacroNomic: <a href="http://www.nomic.net/deadgames/macronomic/" rel="nofollow">http://www.nomic.net/deadgames/macronomic/</a>
When I taught high school, nomic was the day-before-vacation time waster in my CS classes. I think we actually had a winner once in the couple of dozen times we played, but the kids had fun. They sat around arguing about logic, which was a very easy sell to my administration.
For those with a shorter attention span, there's an addictive card game in which changing the rules is a move: <a href="http://www.wunderland.com/LooneyLabs/Fluxx/" rel="nofollow">http://www.wunderland.com/LooneyLabs/Fluxx/</a>
This sounds a lot like the semi-popular college game 1000 Blank White Cards (<a href="http://en.wikipedia.org/wiki/1000_Blank_White_Cards" rel="nofollow">http://en.wikipedia.org/wiki/1000_Blank_White_Cards</a>)
This brought back fond memories of calvinball <a href="http://en.wikipedia.org/wiki/Calvin_and_Hobbes#Calvinball" rel="nofollow">http://en.wikipedia.org/wiki/Calvin_and_Hobbes#Calvinball</a>
Hofstadter wrote about this in a column for Scientific American. The article appears in his collection, "Metamagical Themas," and Google Books has most of it here: <a href="http://books.google.com/books?id=o8jzWF7rD6oC&dq=metamagical+themas&printsec=frontcover&source=bn&hl=en&ei=TQ7TS5ryBoKC8gaRx625Dw&sa=X&oi=book_result&ct=result&resnum=5&ved=0CBsQ6AEwBA#v=onepage&q=nomic&f=false" rel="nofollow">http://books.google.com/books?id=o8jzWF7rD6oC&dq=metamag...</a>.
Nomic is a fascinating game.<p>For those about to try it in school: You should probably add a fixed rule about not ending class prematurely and going outside to play (my students needed a rather long time to come up with this loop hole). But it was an interesting hour which served as an introduction to the 10 commandments.
Sounds really cool. I wish I could find a group to play this with. Any takers in NYC?<p>In other news, all these numbered rules made me think of Rule #34. I lost.
