Keyboards for efficient input on PDAs.
See some of the best
keyboards. Words are formed by gliding the stylus from one letter
to the next. The boards were formed using simulated annealing with
letter frequencies from common English (s and z
represent leading and trailing spaces, though either can be used for
'space', or a twiddle back over them for double space). Generally the
keys naturally align themselves to a hexagonal grid.

"Measure" class which handles physical
dimensions (mass, distance, time) and a 3-D "Vector" class that uses
it, for building physical systems in a structured, error-checking way.
Unsure status. Contained in Zip
file.
Partially constructed "ClockMaker" system for allowing
students to construct and simulate clocks and other physical systems
using a combination of physical abstractions and collision-dection
mechanisms.
3-D Differential Equation Programming System, allowing one to
state interrelated equations in programs and use their solutions.
Final project for C++ class (buggy?).
Elegant model of the double pendulum, written using the
scheme mechanics package.
