How would you open a knob-less door? Does it even exist? Well, wonder no more because American architect Karim Rashid came up with a brand new way of opening a door: Ring Door! The door reminds me of a black hole... sucking in everything it sees! I can see this door in a minimalist environment where owner wants everything super high tech. Remember that MTV Scream by Michael and Janet Jackson? This door would have been in that video had Karim designed it then.
