The Hat Lamp is simply just that, a pendant lamp shade in the form of a hat. Created by Mars Hwasung Yoo, this pendant was made to encourage people to think outside of the box. Every day objects that we take no notice of are now turned into having a completely different purpose. This is most definitely a piece that will make observers think and spark creativity.
Accompanying the Hat Lamp is the Cap Lamp, a desk lamp that resembles a baseball cap. Both these lamps bend our minds to see different possibilites for various objects we see regularly.
