Build yourself a solar powered office out of a Tuff Shed, giving yourself a workspace to maintain isolation between your work and the rest of your life.
This tiny circuit will annoy friends and family with its piezo buzzer that makes unwanted sounds, and an LED that will blink in the wee hours of the night.
Press down on this origami frog and the LED eyes start to glow. Release it, and the frog will leap across the table (sometimes even flipping in midair).
