AMUSEMENTS

So you figured out Rubik’s Cube, eh? Well, get ready for Rubik’s Clock--a puzzle the Hungarian professor says he hasn’t even solved yet, a spokeswoman for the toy company marketing the product said Monday. But Erno Rubik’s failure has not arisen from a lack of ability, merely a lack of time to puzzle out the secrets of Rubik’s Clock, said Melanie Bateman of Matchbox Toys Ltd. “Really, it’s not because it’s impossible, he’s just too busy to take the time to do it,” she said, adding that the new toy will be launched at a major London toy store on Saturday. What can you expect to pay for more hours of mental anguish? About $12, Bateman said.
