Are we talking DeCSS? I'm wearing it now (hey, it's one of my only white
t-shirts, and I had to do a quick white load to tide me over to
payday...). Yes, I HAVE worn it in public, and yes, people have noticed
it. Mostly because it's in C (we used the Johansen css_auth.c code with a
few things #define 'd to fit), but some actually knew what I was doing.
The perl code is too new to have printed yet: it took us about 2 weeks to
get our batch of css_auth shirts done, but YMMV.
