At first you see a collection of gizmos, each connected to a rhyme. Choose a gizmo and explode it into its separate pieces and a dot will start to dance along the words of the rhyme attached to it, just as a nun runs her fingers slowly along the beads on her rosary as she prays. Click a piece of the gizmo and it appears in your building area, bringing with it the word that the dot had reached when you clicked. Choose another piece, and another, and soon you’ll have made both a new gizmo and a new sentence built from the pieces you took apart.
The links are down for the moment, but I’m blogging this so I remember it and try it later.
