Robotic hamsters. I wish I could leave it at that. The imagination runs wild with the possibilites presented by those two words.
Alas, the robotic hamsters in question are "just" one of the Christmas season's hottest toys, according to The Financial Times. You can have your very own "Zhu Zhu Pet" for $10, if you can find a store that has them in stock.
They have names, too:
The interactive hamsters, Mr Squiggles, Patches, Chunk, Pipsqueak and Num Nums, respond to touch with squeaks and noises, and can be set to run about randomly in "explore" mode, or to "coo and chirp" calmly when held.
