The following two emails were sent to me by the fabulous ToniTwiss for your edification. The article on philosophy in the previous post was also from her.
"You may have seen this but thought your kids might be interested
is very funny - and is along the lines of people getting frustrated with people (ie. the whole of NZ) giving Hamilton a bad name"
"After reading your students' post about gravity I found this game
You are the little yellow ball that you have towards your goal. You have a knife and have a certain number of cuts you are allowed at each level. Some objects can be moved but not cut, so for example if you are on a piece of wood you can cut that and it will fall therefore because of gravity the ball will start to roll too. I made it to level 3 - but I am not very clever!"
