USB stories

From Japan's Hum design studio comes this little gem, the "hum blank." Looking at this, do you see a bottle that's completely empty, or one that's filled to the brim? Both perceptions are correct, and are right at the same time. Whoa.
Puzzle and security freaks will love the new Crypteks physically lockable USB device. The USB storage is located inside a housing with five rings on the outside, each set with the 26 letters of the alphabet. Twist to your code and you've unlocked your USB. With 26 letters and five rings, you'll have whopping 14,348,907 possible passwords. Now that's security!
