	SIGGRAPH 99 Special Interest Group on Computer Graphics Los Angeles, California USA 8-13 August 1999 1999 ACM 33kb curlybot Phil Frei, Victor Su, and Hiroshi Ishii Tangible Media Group MIT Media Laboratory 20 Ames Street, Cambridge, MA 02139 USA {frei, vsu, ishii}@media.mit.edu ABSTRACT Recent trends of embedding digital technology in toys have led to greater possibilities for manipulation and interaction. We are designing toys that can exhibit complex behavior in response to simple physical manipulation. "curlybot" is a two-wheeled toy with embedded electronics that can record and playback motion. As one plays with it, it remembers its change in position and can replay its movement forwards or backwards with all the intricacies of the original gesture. Every pause, and even the shaking in the user's hand, is recorded. For this presentation, we will augment the interaction experience by projecting trails behind each toy. The trails will give participants a chance to not only play with composing a movement or a dance, but also with creating graphical patterns out of simple gestures.
