There's a pd or shareware Type 1 font (in Mac format, but see
previous articles on fixing that) called Recycle which has
many different recycle logos, including all the ones for plastics,
with the correct numbers inside. Last time I checked, it's on
sumex-aim.stanford.edu:info-mac/font.

If somebody's desperate for this font and can't get it out of
Macintosh format, I can probably help.

Bill took his 'standard' from a can of Diet Coke, according to his
earlier post; but I have in front of me a (UK) can of Diet Coke, and
the 'recycle' logo is SYMMETRICAL!  All three arrows go from 'behind'
to 'in front' - just like the one printed by John's recycle2.ps file.
A quick check around the office shows that ALL the products here
bearing a 'recycle' logo - drinks bottles, toner cartridges, toilet
roll wrapper, C++ modules (:-) - use this same symmetrical logo.

So this could be a matter of national standards not matching; perhaps
some other people around the world could tell us what their 'recycle'
logo looks like, for comparison.

The recycle symbol is meant to be a mobius loop.  It is
meant to symbolize an infinite loop, i.e., infinitely
reusing something that is recyclable.  The Government of 
Canada chose to go with the variant that *is* a mobius loop.

With this version, if you carefully follow the surfaces of 
the arrows as they go from front to back around the loop, 
you will return to your starting point after going around twice.
That is, after going around once, you will be on the surface 
on the other side of the arrow.

The recycle symbol that has all three arrows the same
is not a mobius loop.  You will return to your starting
point after once around, and you will never get to the
other side.
