Robbie the Calculator
It might not be the most advanced scientific calculator in the world, but how how many calculators do you know come with arms and legs!
This calculator does it all. Not only does it look like a cool semi-retro robot, but it can add and subtract and multiply and divide. But unlike ordinary calculators, this one has hands and feet. The feet will let it stand upright and the hands will let it hold things (like pens, cables, or the included LED light).
TG have the robot calculator for sale at $14.99.
