funpart is a toolkit for Monte-Carlo simulations for particle transport in Haskell. It is vaguely inspired by Geant4 and TRIPOLI-4®. It is really supposed to be:

1. A demonstrator for scientific computation in Haskell;
2. An easily extensible tool to make it possible to quickly test a new transport algorithm, variance-reduction method, etc.;
3. A sandbox to play around and learn more Haskell in a realistic setting (that's the fun part — pun intended).

It is not (yet) supposed to be:

1. A realistic alternative to existing particle-transport codes;
2. A tool for world domination.
