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.

No details on where one outside Japan could pick up this deliciously simple design, though this Japanese store seems to carry the corked drive for 3,465 yen, or about $43. The drive is listed as having a 2 GB capacity, so you're paying a premium for design. (In this case: worth it.)
