If your kids like tinkering and dreaming Transformer dreams, take the tikes to the Foundry to build a low-tech robot of their own. The machines made out of tin cans and pipe cleaners won't walk or think, but with a little imagination they can be cooler than robots vacuum the floor or make cars. Grown ups can enjoy the toys at parties and corporate events with food, drink and vibrating little gizmos of your own design.
