I've been thinking for around two years about this one, and I think it is
a semi-possibility...

Here are the steps for making it:

1. Take a piece of flexible material in the shape of a triangular prism:

  +------ must be equilateral! 
  V
   _______.___________________________________________________________
  /\     /|\                        <--- about 30cm --->              \
 /  \     |  about 3cm                                                 \
/____\___\|/____________________________________________________________\
          "

2. Take one end, twist it through 120 degrees, and stick it to the other
end (making a circle when viewed from above)

(I tried this in ascii. I didn't manage it :) )

3. Stretch the loop over 3 nails, arranged at the points of an equilateral
triangle:


                                    O

                                 /     \

                               /         \

                             /              \

                           /                  \

                         O <-- about 9.5cm --> O
                     
4. Fiddle with it until it looks like the diagram at the top of this
message...
