From here:

An Edmonton woman is fighting for the right to proudly display her facial piercings without fear of professional punishment.

Kendra Behringer has pierced her ears, eyebrows and lips in an act of “self-expression.”

However, she believes her appearance has cost her jobs, something she hopes to change by launching a petition slamming workplace discrimination against tattooed and pierced employees.

If Behringer is successful – something that wouldn’t surprise me – she may open up a new opportunity for Christians who have been harassed for wearing a cross at work. Punch a hole in your eyebrow, stick the cross in it and you will be OK.

I’m sure that if there are theological implications to wearing an eyebrow cross, Rowan Williams – who may already have several for all we know – would be only too happy to elucidate them; I know, I know, writing “elucidate” and “Rowan Williams” in the same sentence is the essence of oxymoron.
