+Dave says the Faerie Queen, black holes, and time warping were in the
+original. However, either he is misremembering about time warping or
+the original implementation was lost during the FORTRAN-to-C
+translation, as Stas Sergeev added a time-warping feature not
+previiusly present in 2006. Tom Almy also claims to have added
+timewarping!
