Entering a new field is a fun experience. You start off by thinking "Wow, why has no-one done this before?" Sometimes, you've hit a new idea, and become a pioneer. Sometimes, you find a few similar attempts, but are still in unexplored territory. But what often happens is that you find there are entire conferences dedicated to the idea, and you simply hadn't heard of them. The world's a pretty big place, so this happens a lot.

Google for "program comprehension tool," and you'll see there's no shortage of tools to help people read code. Rather than create another one, someone should really just look at a bunch of those and create a "Top 10" list.
