British designer Onkar Singh Kular has created a series of ingenious household objects, including a self-leveling picture frame with a spirit level embedded in it and a pair of socks with an extra thrown in against sock disappearance incidents. Best of all are these "Pantone" mugs whose colours correspond to a specific ratio of milk-to-tea -- you know you've added enough milk once the colours match. Nice.
