Here's a cool new toy trend on top of the webkinz, etc -- Disney's Pixie Hollow has an online component and a physical toy. But instead of it just being about entering a code from a tag, these toys blend real and virtual world together.
How does it work? They sell pixie jewelry with a new technology they're calling "Clickables." If two friends have Pixie Hollow Clickables in the real world, you can click bracelets and automatically become friends in the virtual one. Now that rocks. Forget about sending a Facebook invite to someone you just met, instead let's have a social network blue tooth keychain dongle or phone app which allows you to just insta-friend. Nice!
