It is based on the belief thatcreativity is an automatic outcome of the existence of sufficientlyflexible and context-sensitive concepts --- what we call fluidconcepts. Accordingly, our goal is to implement a model of fluidconcepts in a challenging domain. Not surprisingly, the Letter Spiritproject is a very complex undertaking and requires complex dynamicmemory structures, as well as a sophisticated control structure basedon the principles of emergent computation, wherein complex high-levelbehavior emerges as a statistical consequence of many smallcomputational actions. The full realization of such a model will, webelieve, shed light on the mechanisms of human creativity.The specific focus of Letter Spirit is the creative act of artisticletter-design. The aim is to model how the 26 lowercase letters of theroman alphabet can be rendered in many different but internallycoherent styles. The program addresses two important aspects ofletterforms: the categorical sameness possessed by letters belongingto a given category ( e.g., `a') and the stylistic sameness possessedby letters belonging to a given style ( e.g., Helvetica). Startingwith one or more seed letters representing the beginnings of a style,the program will attempt to create the rest of the alphabet in such away that all 26 letters share that same style, or spirit.</BLOCKQUOTE><P><STRONG>Associated Faculty: </STRONG>Douglas Hofstadter <P><STRONG>Associated Graduate Students: </STRONG>John Rehling<P><STRONG>Affiliated Projects: </STRONG>Metacat (Douglas Hofstadter & Jim Marshall)<P><STRONG>Support: </STRONG>This research is supported by funding for the Center for Research onConcepts and Cognition (CRCC) provided by the IU College of Arts andSciences.<P><STRONG><!WA0><AHREF="http://www.cogsci.indiana.edu/farg/mcgrawg/lspirit.html">Moreinformation</A></STRONG> <P><!WA1><A HREF="http://www/research/index.html"><!WA2><IMG SRC="http://www.cs.indiana.edu/hyplan/fleisher/back.gif">Return to IU Computer Science Research</A><!-- or use HREF="http://www.cs.indiana.edu/research/index.html" if your page isn't served by the CS Dept server --></BODY></HTML>
