Sometimes improvements on the most minuscule objects around the house can hit you like a ton of bricks, creating an entirely new market for items nobody has ever paid attention to nor thought about. Take Justin Porcano's work for example; his Wallplate turns regular lightswtich plates into massive drool appeal by creating functional drop boxes for mail and keys. Clever? You betcha.
Update: Correction, it's Justin, not Justine! Apologies for the typo!
