If you laminate up a square blank with contrasting timbers you definitely get a striking pinstripe effect. (just turn it up as a solid timber blank). Alternatively, you could easily do a string inlay with a contrasting timber or even silver or gold inlay if you want top shelf bling. There are many options to consider. You could for example cut alternate wedges in contrasting timber and glue them back into a solid round, then machine as normal. This would give a very even pin striping effect. Lots of options, none too hard to execute either....
