       A warning to DEEPZOOM users.

Few can forecast the effects of technology on our futures as well 
as Arthur C. Clarke.  Since he has written of at least one who 
zoomed too deep once too often, we might want to be careful.  In 
his 1990 novel _The Ghost from the Grand Banks_, he describes one 
Edith Craig at the Torrington Clinic for psychological disorders, 
who is mentaly locked in a 40 digit deep zoom into the Mandelbrot 
Set.

Hmmmm.  There are now about 70 who have gotten my DEEPZOOM program.  
In the novel Clarke notes that "there are no less than sixty-three 
examples of Mandelmania now in the data banks."

Warmly,
