In past years students mainly built very simple long "trains" of these linking cubes. Sometimes color patterns would emerge in the chains.
This year I'm seeing much more interesting three dimensional objects. First to appear—predictably in our militarized culture—the usual space craft and contraband weaponry: guns, that turn into light sabers; light sabers that turn into lethal "flashlights" and the sort.
But, happily, we're seeing other things, too. Animals, even!
