Located in the cavernous main hall of the Museum of Fine Arts, Houston, "Shadow Monsters" is a clever and whimsical interactive art exhibit that kids have to see to believe. Using projectors and a vision-recognition program, you can transform your shadow into an ever-shifting monster on one of the three walls. Your limbs and head will sprout eyes, tendrils and teeth as you move, and there are bins available full of props to help you create even more impossible shadow visions. Warning: It can be a bit frightening for little children, but most get into the piece fairly easily once they discover they have complete control over their own nightmare images.
