It seems crazy, but this is clever and fun. It's like an inside
view of what's happening.

Dangers of computer controlled anything: Therac-25

http://en.wikipedia.org/wiki/Therac-25

This is the classic case of what can go wrong:

It was involved with at least six known accidents between 1985 and 1987, in which patients were given massive overdoses of radiation, which were in some cases on the order of hundreds of grays. At least five patients died of the overdoses. These accidents highlighted the dangers of software control of safety-critical systems, and they have become a standard case study in health informatics.

I wrote a lot of assembly language control systems, but I was always glad they were not in a place to endanger lives.
