A correspondent just sent the following - any comments anyone?

> The Swiss 10 Fr note has some graphs on it that are accompanied by what

> the sequence seems to be spliced together from two sequences (since the
> odd numbered terms are in one color and the even numbered ones in another)
> and in each of the sequences, the ratio of successive terms is
> suspiciously close to the golden ratio.  Actually, I just noticed that
> each odd numbered term is the sum of the two preceding odd numbered terms,
> but this is not quite true of the even numbered ones.
