[time-nuts] Worlds first time code generator and ultimate decoder

[Max Robinson]

The issue of the recording stylus apparently moving backward along the time 
axis shouldn't be a mystery to anyone who remembers the old Brush (brand 
name) galvanic chart recorders.  The pen tip moved in an arc rather than 
rectilinear and for slow paper movement the graph appeared to move backward 
in time.  I have no idea exactly how virtual stylus works in decoding these 
recordings but it seems possible that they could account for the recording 
stylus being moved in an arc rather than a straight line.

Regards.
