Prototype 1: Floppy Legs
Portable hard drives are vulnerable to desktop spills. Floppy Legs has a set of moisture triggered legs embedded within it's body. If it senses liquid nearby it will quickly 'stand up', distancing itself from the threat. This gives the owner time to move the hard drive away from the liquid, out of danger. When the coast is clear the device gently lowers itself back down.
Prototype 2: The Gesundheit Radio
A radio sits on a shelf, gathering dust. If it goes unused for a long period of time, the dust can ultimately cause it to stop working. The Gesundheit Radio solves this problem by periodically cleaning itself out with a mechanical 'sneeze' (the sneeze can also be trigger manually).
Prototype 3: Antitouch Lamp
It's not a good idea to touch a Halogen bulb. a) They're extremely hot, and b) touching them with bare hands dramatically shortens their lifespan. A motion detector in the base of the Antitouch lamp hopes to address this. When it detects someone nearby it sways away from them to avoid being touched.
