Here are few applets and such that I have worked on in my spare time. 

Most require a JDK 1.1 compliant browser like IE 4 or Netscape 4. 


Animation of a Prenatal Madeleine (requires JDK 1.0)

This is an animation of images that I digitized from the ultra-sound tape. 
Madeleine was about 7 months along.  This is the same as the animation on the Pics page.

Mandelbrot Set (requires JDK 1.1)

A fractal is a rough or fragmented geometric shape that can be subdivided in parts,

each of which is (at least approximately) a reduced-size copy of the whole.

The most famous fractal is the Mandelbrot Set. The set is defined as those values of C which when iterated
according to the complex number function Zn+1 <- Zn^2 + C with 

initial value Z= 0 + 0i result in a sequence  that does not  go off to infinity.


Merge Sort (requires JDK 1.1)

Visualization of a Merge Sort.



Insertion Sort (requires JDK 1.1)

Visualization of an Insertion Sort.
