I feel inspired to take it on. I have questions on how they pictured it because it could be implemented in quite a few ways.

I've forked it and made changes as well as submitted a pull request to Sontek.

Okay, I have a working prototype of a snowplow idea, it took me a long time to wrap my head around how things were rendered to the screen and how it kept track of snow particles.

Now I am going to work on a few bugs and clean up the code so I can either fork it or submit a pull request.
