Soon there shall be a trendy fashion for improving the feng shui of
tiled floors by using more organic materials as tile spacers, perhaps
timber. Of course these would need to be dipped in something oily first,
to stop the adhesive sticking. We could even sell these in handy
pocket-sized boxes, for a fraction of the price of the plastic spacers.

You could even dip the ends in phosphorus and create a dual purpose spacer
that could be used to light barbecues or candles.
