You don’t need to spend big bucks to incorporate genius into your life. “Brilliant” lurks in unexpected places, like the range of wildly kooky (and cheap) things right on Amazon. We gathered up the weirdest and also handiest finds — the ones so useful we can call them brilliant. From sculptural toilet paper holders to touch-control lamps with big mood, every weird find here goes to show that you don’t have to sacrifice practicality in favor of personality. Better yet, they start at just $5.
