Hourglass Lantern

Link certainly would have loved to get hold of this instead of the Phantom Hourglass as it will help him find his way through dark dungeons. The Hourglass Lantern looks like a traditional hourglass, but it ditches sand in favor of LEDs instead. You can choose to set just how long it takes for the light to flow from top to bottom simply by twisting the two halves like a dial. Every minute that passes by will decrease the luminance on top, while the bottom one gathers more light. Anyone wants to see this design by Young Bok Kim become reality?
