Dear Hypercubists,

Thank you for your votes of support and for all the other indispensable help you’ve given that made the puzzle possible in the first place. I’m deeply moved.

>> Subject: 4D Pocket Cube Nomination
>> Dear Mr. Bailey,
>> I just got your letter recommending the 4D Pocket Cube for the National Toy Hall of Fame. Thank you! I have forwarded the information to our chairman for the nomination committee and the cube will officially get a nomination. The best advice I can give you at this point is to get your friends and other fans of the cube to go online and nominate it as well. And you can also vote yourself—I think the limit is once daily but not sure about that. The more votes it gets, the more likely it will be to finally get inducted. I assure you that all the votes get counted, and they become one of the stronger factors for eventual induction.
