These applets were implemented
through the years 2004 and 2005,
based on the JCM open source library.
The four applets in the second and third columns
are also evolution graph sketchers.
The abstract dynamical model behind them has been further generalized
to include both discrete/continuous time,
and discrete/continuous state space.
Except for applet 'Linear Fractional Functions', which is pure JCM,
they all use a typesetting package that I developped to display,
and dynamically change, simple mathematical formulas.
