We don't have a sense of scale for the very small, and gigapan + microscopes (optical or SEM) can go a huge way towards opening the country of the very small to a wider public. Richard Feynman wrote There's plenty of room at the Bottom, but even if you have read that (more than once :-), you still don't get the sense of what 'small' means that you can get from seeing it in a Gigapan.

imaging the imager
The subject of this micro-gigapan is the optical sensor of a canon powershot G1. The chip is about 8mm long and 6mm wide. While the entire length of the chip was captured, only a small portion of the width was imaged due to the highly repetitive pattern of the light sensors.
The focus stacking feature has still yet to be implemented on this microscope. As such the chip had to be very level with imaging plane. The chip was leveled using a two degree of freedom rotation stage.
