Optical Illusions for Prof. Virginia de Sa
These illusions are written to satisfy an NSF grant. The illusions are
for a children's science website, Whyville. Because children might be using
older computers and older versions of java, these illusions are written to be
low resolution and compatible with java 1.1.

Development of these interactive illusions was supported by the National Science Foundation under CAREER Grant No. 0133996. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author and do not necessarily reflect the views of the National Science Foundation.
