Today my coding period has started.
Some initial code is darcs-pushed to
http://code.haskell.org/hpysics. Now I want my mentors to look at the data structures I've defined and tell me if some of they won't play nicely with NDP.
Then, my nearest plans are to get basic collision handling working. Also, though I planned visualization for the late June, I probably will do it earlier -- it's very tempting to see your physics engine produces plausible results.
