Ok, so it's not a computer craft, but we bought the Stix Sparx for our bikes and these wands were so cool we decided to offer them as well!! Also check out the Sparx Stix! Light up the party with the Mini Rainbow Wand featuring the Patented True Rainbow LED When the wand is still the LED appears a vibrant white, but wave the wand and the full spectrum of the rainbow creates a cool lighting effect Push the button on the side of wand to activate LED LED automatically turns off after about 20 seconds Pocket sized wand comes with attached keyring for accessorizing bags or keys (3) AG10 batteries included and replaceable. rainbwnd Rainbow Wand Keychain rnbwkey$4.99 The Crafty PC - Matching Your Creativity with Today's Technology Copyright © 2000-2011 The Crafty PC, LLC.
