Only one change: use "kiosk" argument (similar to scale:2) to enable fullscreen, this should solve the size issue and prevent from drawing off the Window, if I have time later on today, I'll work on increasing the size of some of the buttons you mentioned.
Sure XX, i use OE-cake also, and the kids love the fluid effects of using water and other viscous materials. Can't find the full version of OE-cake anymore though.
interactive white boards make any flash game or small simulators an instant hit with my class. I admit that it is fun to have huge screen to play around with using the particles in powder toy.
In China my older students are more familiar with the physics of the simulator, and are really draw to it.
Chinese students have a lot of pressure and having a sandbox game I think lets them loosen up and enjoy themselves while the parents are content they are learning something. Usually they are presented puzzles and problems to solve all day. With powder toy there are not problems to solve except the one's you choose to create.
A great way to encourage creativity with a kinesthetic approach to learning.
EDIT - Thanks Simon. I download the test game, but how to apply the "kiosk"?
At my school, the ICT technician repeatedly attempts to block it, but since there are 30+ versions available for people to use at my school (only 3 of them are regularly used) he's given up.
you could get rid of some elements like plut and other radioactives, and most of the electronics section to make room for new kid elements like rainbow or cloud or bouncy-balls.
