Drug design is a creative act of the same magnitude as composing, sculpting
, or writing. The results can touch the lives of millions, but the creator
is rarely one scientist and the rewards are distributed differently in the
arts than in the sciences. The mechanisms of creativity are the same, i.e.,
incremental (plodding from darkness to dawn) or sudden (the "Eureka" effec
t) realization, but both are poorly understood. Creativity remains a human
characteristic, but it is directly related to the tools available, especial
ly computer software and hardware. While modelling software continues to ma
ture, very little new has evolved in terms of hardware. Here, we discuss th
e history of molecular modelling and describe two novel modelling tools, a
haptic device and a program, SCULPT, to generate solid molecular models at
atomic resolution. (C) 2000 Elsevier Science Inc. All rights reserved.
