Hannah Fink is making flat-pack furniture that's built to last. Her Fink Side Table is made of three slotted steel panels that ship completely flat and require zero hardware to assemble. Finished with a scratch-proof coating, you can disassemble and assemble it as many times as you need.

Riding the Sony Walkman nostalgia wave, NIMN Lab's IT'S OK cassette player combines the retro technology with Bluetooth capability. You can listen to your favorite tapes and perform all the typical cassette player functions, with the added benefit of using your wireless headphones or linking to a Bluetooth speaker.

Plants let us know how they're doing via subtle changes and clues but it's not always easy to figure out what they're trying to say. The Lua planter aims to bridge that communication gap and turn your houseplant into a "virtual pet." Sensors within the planter measure several factors—the soil's moisture, light exposure, temperature, humidity—and display what your plant is feeling via cute little animations. When it's dry and thirsty, it will stick its tongue out and pant; if you put it by a drafty window it will express its dissatisfaction by shivering; and when it's doing just fine it will smile contentedly and wink at you.

Available in three intricate designs, David Sze's Humism watches bring kinetic art to your wrists. The automatic timepiece features two to three rotating discs that create a mesmerizing, kaleidoscopic movement.

The Forge 3-Way-Pack is inspired by a staple of Tokyo commuting culture, a bag that can quickly be transformed from a backpack to a shoulder bag to a briefcase, depending on the needs of the day.
