My Grandma Gregson made us all one of these made out of notebook paper she had colored with crayons. Inside there was a handwritten note for us. The baskets are open at the top, so you can add tiny little lightweight gifts inside if you choose.
Kaleidocycle - SUPER COOL! Printable template and instructions. There is an origami version of this in Steve and Megumi Biddle's book "The New Origami." They call it a rotating tetrahedron. Also check out FoldPlay: http://foldplay.com/kaleidocycle.action;jsessionid=C62E6EE1F29B2734CE3839D6D993D2B2 where you can print your own images to make a kaleidocycle. VERY COOL.
