All this infinite record stuff is driving my little brain batty....

(you must view this in a fixed-pitch font)
---------------------
A turntable spins
this way:


    /^^^^^^^^\
   /          \
  /            \
 |      /\      |
 |      \/      V
  \
   \
    \___

---------------------
A inward-playing
groove for a forward
spinning turntable
looks like this:

a)    /^^^^^^^\
     /  /^^^\  \
    /  /     \  \
   |  |  /\   |  |
   |  |    |  |  |
    \  \__/  /  /
     \      /  /
      \____/  /


---------------------
A outward-playing
groove for a forward
spinning turntable
looks like this:

b)    /^^^^^^^\
     /  /^^^\  \
    /  /     \  \
   |  |   /\  |  |
   |  |  |    |  |
    \  \  \__/  /
     \  \      /
      \  \____/


---------------------
To connect the end
of a) to the start
of b) at the center
of the record (and
to connect the
beginnings on the
outside edge) still
looks impossible to
me without crossing
grooves many times.

c)    /^^^^^^^^^\
     /  /^^^^\   \
    /  / /^^^^\^\ \
   |  | |  /\  | | |
   \  | \_|_/  | | |
    \  \   \__/ / /
     \__\______/ /
         \______/


---------------------
BTW, I'm not even
stoned.
