I spent about an hour working with the applet, which allows the user to build
a variety of series LRC circuits and observe the transient behavior. The applet
is rather well done, and qualitatively and quantitatively illustrates the
physics of this class of series circuits rather well. It has an unusual display,
showing the voltages at the nodes by tilting the circuit. This is clever, but
probably will need to be explained to most students.
The display of (t,V) points would be more quantitatively useful if it showed
only the actual values of V for a given t, and only when the mouse pointer is
close to the plotted voltage curve. As is, the graphs are hard to see on the
gray background, and cannot be used for consistent quantitative measurements.

Technical Remarks:

The major problem is that the calculations are unstable for some values of
circuit elements and time scales.

A very clever approach to the circuit problem, and one that gives the user
plenty to experiment with. Applet takes a long time to load, but runs very
well. Highly recommended.
