This jacket has a learning curve that seems to approximate mastering Tai Chi. That won’t likely be an issue for gamer girls and guys. Built-in (but removable for washing) sensors and light strips all hook together and respond to specific body movements to generate an astonishing variety of “spells” with corresponding sound and light effects. Plan your environment to enhance the effect, but be sure to have lots of Mana on hand for refreshment. Technomancer 2.0 Digital Wizard Master Jacket. thinkgeek.com.
