This is probably too complicated for most of us (certainly above my pay grade), but I thought it was pretty cool:

. Now for the first time ever, researchers at the Luxembourg Centre for Systems Biomedicine (LCSB) at the University of Luxembourg have published an interactive picture containing the current knowledge about the underlying genetic and molecular causes of Parkinson's disease. This "Parkinson's disease map," or "PD Map"

Marek Ostaszewski sums up the most important benefit of the PD Map: "By uniting the existing knowledge about PD, the map sheds light on the connections between pieces of the puzzle nobody had thought existed - and which will form the basis for brand new research hypotheses." To the biological scientists the PD Map helps pinpoint the gaps in our current understanding of Parkinson's.

The other cool thing about this project is that the researchers are making it open-source like WikiPathways.
