It looks just like a regular (and admittedly slightly boring) calculator. What it won't do is jazz up your desk space. What it will do, however, is save on regular batteries, working entirely from water-powered, totally recyclable batteries. The water only needs refilling every 2-3 months, which sounds pretty low maintenance to me. But how much water is needed, where it is stored, and whether it can spill all over your newly-printed report due five minutes ago, I don't know.
A good choice if you want to save the planet in secret without risking a reputation as a tree-hugging leftie.
