Sick of people invading your personal space on public transportation? Industrial designer Siew Ming Cheng invented the Spike Away vest to ensure that no one gets too close for comfort. The vest certainly won’t attract any potential dates, but it looks like it could be a futuristic piece of high fashion.
Cheng got the materials for her prototype from an unlikely source: a hardware store. It’s made of off-the-shelf strips designed to keep pests out of gardens. The Spike Away vest is just a concept, but it’s useful enough that we could imagine it flying off of the shelves if it ever became a real product.
