Thought this article was pretty cool for a finals project:

The idea was to launch my system into the stratosphere to an altitude of about 100,000 feet (30,480 metres) using a weather balloon. At that altitude, it could take pictures (hopefully) showing the blackness of space above and the curvature of the Earth below.

Bit of an interesting read.
